Do coral reefs really matter though? Sure, it's a milestone, but not an existential one.
Yes, they absolutely do matter, and yes it is potentially an existential one. Coral reefs are the most biodiverse part of the seas and are the source of many of the ocean nutrients that get carried around the globe on currents like the AMOC, so they play an essential part in the overall ocean food chain that many people rely on to survive. Removing the coral reefs from those people's food chains would be akin to the impact of removing Alfalfa from the US food chain that ultimately leads to all that beef and dairy produce.
Also, if their primary food source is unable to support them, they're not likely to stay put and starve for the greater good, are they? Where do you think they are going to start marching towards?
