This seems like a pretty niche feature set, so if anyone does make it, expect to pay a lot more for it. But I really don't understand some of these requests, and sound pretty stubborn. Here's my take on each:
Seems nice in theory, but all it does is take up more space that could otherwise be used by a bigger, longer lasting battery. It also creates restrictions in where components can be placed, because the battery must always be accessible to the user. But there are workarounds for non-removable batteries. If battery life is a concern, you have battery extending cases (where there is an extra battery built into the case) or portable chargers you can throw in your bag. If you are worried about replacing a battery that no longer holds a charge, you could still replace the battery, just a little more involved. Really only something you should need to do every 2 years or so.
2. Physical keyboard (e.g. BB KEY2)
Every once in a while someone comes out with one, and the market overwhelmingly rejects it. All of my friends/colleagues who are former Blackberry die hards have moved on and never looked back. Typing on a tiny physical keyboard has never been pleasant. Learn how to use Swype. It is much more efficient. Compared to a physical keyboard, it is faster, easier to do with one hand, and also pretty easy to do without looking (still should proof-read, though, but that's the case no matter what type or size keyboard).
Define "ridiculously". It needs to fit in your pocket right? That's where most people keep their phones. Thinner means you can fit more in your pocket. If you say, "well I'm just going to slap a giant case on it anyway like an otterbox", well, then I guess thin is even more important so that a phone+case doesn't take up too much room. Is thin ever a detriment, though? It may not be important to you, or a major selling point, but do you actually have a minimum thickness that you simply could not ever go under?
4. Not ridiculously large
I'm with you on this one. I have smaller hands and I like to one-hand my phone. I used to travel a ton for work, so I needed something I could use while walking through an airport dragging a carry-on behind me. 5 inches is my max. I really liked my 4.7" original Moto X, though. That was perfect. Luckily, manufacturers seem to have gotten the message. Pixels, Galaxies and iPhones all come in 2 sizes now and the smaller one isn't just a cheaper, slower, inferior in every way version of the bigger one. Hopefully this trend continues and other manufacturers with more differentiated feature sets follow.
I'm curious about your issue with an infinity edge. You don't want a phone that's ridiculously large, so an infinity edge only helps with this. You can pack more screen real estate into a smaller overall phone. If you mean like the screens Samsung has on the S9 and introduced in the "Edge" series, I get it, but Samsung is the only one doing this, so not hard to avoid them.
Legitimate complaint. I'm not a huge fan either, but I'm warming up to it. I guess it depends on how you look at it. Does it take away usable screen space, or does it open up more screen space that would otherwise be a large bezel? Again this goes back to size. You don't want ridiculously large, but this is a way to pack more into a smaller size. There is a lot of experimenting going on here (that's essentially what this article is about - Samsung is trying out a bunch of stuff to see what sticks) and I like the way OnePlus has kept it minimal. At the same time, though, I thought the very slim bezels on the Pixel 2XL, Pixel 3 (small size) and Samsung S9 are really nice and didn't see a need to gain an extra few millimeters.
7. No headphone "courage"
I'm with you here... for now. And I say this as someone who has a "courageous" Pixel 2. It's honestly my only gripe with the phone. I like the ability to just plug into any AV system and play my music, but now I can't unless I have my adapter with me. I think this will not be as much of an issue once the world around us adapts. USB-C everywhere would be a good start. I see this akin to when Apple killed Flash. A pain for many in the beginning, since so much was flash based, but once the incentive was there to move to HTML5, we are now in a much happier Flash-free world. That's my hope for the headphone jack at least. Maybe I'm too optimistic.
8. No AMOLED (IPS please)
Really curious about your issue with AMOLED. It is a much better quality display just visually speaking than LCD/LED and is much better for battery life. Also, if your phone has a notch, you can just turn it off with an AMOLED. Black on an AMOLED is literally turning off the pixels and they don't use any energy. This makes the ambient displays very nice as well, since you can have the time and notification icons lit up constantly with very little battery consumption. If part of your need for a removable battery was to extend battery life, well this is one step towards not needing the extra battery. AMOLED should be a requirement instead of a deal-breaker.
What's your issue with a front camera? Don't need it? Don't use it. It's not hurting you. You may not like taking selfies all the time, but if you want to do any video chat, it's a requirement. Front camera is a requirement for 99% of phone buyers, so eliminating it would make a phone way too niche to be marketable.
What is your issue with biometric? Yes, it is less secure than a strong password. If that is the issue, don't enable it. I scoffed at Apple when they introduced it, just like the rest of Slashdot, but I've realized how much more convenient it is now, and consider it essential. Especially if you use your phone as part of a BYOD workplace. Strong (read long) passwords are required, which is a real pain to type in every time. I used to set something really easy to type, but would be super in-secure (eg. "qwerty7"). Bad practice, yes, but I also hated fumbling with my phone so much just to unlock it. Fingerprint solves this and is at least better than a very weak password or PIN.
11. No locked bootloaders
Reasonable request. This list is a year old, but you clearly have many options: https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fandroid.gadgethacks.co...
I was with you in the past, but honestly I prefer without now. Cloud storage and back-up make overall phone storage less of an issue and make it a lot easier to get files on and off the phone to begin with. I use Dropbox, so every picture I take automatically uploads to Dropbox and then downloads locally to my desktop computer the next time it syncs. Anything I want to get onto my phone, I can just download from Dropbox. Having an SD card usually meant sacrificing on-board storage, which meant less room for apps and data. I hated having to manage my storage and moving stuff on and off the SD card. Just get more on-board storage and be done with it. I do agree that the storage upgrades are way overpriced, though. If that is your gripe, it is a legitimate one. If you don't trust cloud providers, try OwnCloud. I've heard good things.
13. Configurable RGB indicator light for notification
AMOLED made the indicator light obsolete. I personally always hated them. I liked it initially, but then it just became this annoying nag. I'd have to turn my phone face down at night or the light would keep me up. Long after I ditched that light, I would occasionally have to turn over my wife's phone because the blinking was keeping me up. My AMOLED ambient display is now my alarm clock and clock display at night. It won't wake me up, but If I do wake up and glance at it, I can see the time and if I have any notifications. Less obtrusive than even the old red digital alarm clock. To each their own I guess. However, if you really wanted that light, and you have an AMOLED display, you could create an app that mimicked it. Going back to the AMOLED benefits, the only section of your screen using power would be that tiny dot.
I'm sure you have your use cases, but I feel we are moving away from IR transmission in general. I can control my A/V receiver, Roku, Kodi running on my PC (connected to TV), and now my new TV all from apps on my phone. None of these use IR. Everything is now either Bluetooth or WiFi based and we are much better for it. No need for line of sight. This gives you more options in arranging your living room and how you place your peripherals and allows you to control things from a different room (e.g. change the song playing on the stereo).
Define "real" GPS. Every phone has real GPS, but they often don't require a full constellation of satellites to work. There's some estimating going on when there is only one (or none) available. For most, that's OK and even preferable. I'd much rather have a "you are somewhere in this area" vs. "no signal". I have a Garmin watch I use for running. It is much more accurate than my phone for tracking distance, pace, etc. and much lighter than strapping my phone to my arm. But I often have to wait to get enough satellites, and I have had instances where it couldn't find any. I wouldn't be surprised, though that you could have "real" GPS on your phone simply through software. The hardware is already all there, it's simply a matter of telling the app you are using to wait for a full constellation and to not use cell tower triangulation. I'm just speculating here, though, so if there are any experts reading, I'd love to learn more.
16. SDR AM/FM ... LF-UHF preferred
I guess you have your use cases. This is VERY niche, though. Expect to pay a premium for it.
Not trying to dismiss your requirements here. I'm actually genuinely curious about some of them. But I would also encourage you to be open minded about some. I think you may actually like the opposite better in some cases.
