That's the thing. They don't make their camera app available to third party ROMs despite officially cooperating with one, and they also haven't made the camera's features available to third party camera apps. So for me, being on CalyxOS myself, that announcement email read like a joke.
I would love for beehaw to stay on lemmy, not necessarily for federation but for my personal ease of use. I understand your issues however and would not be opposed to moving to another base. My main concern would be the availability of an (or possibly several) open source app to participate on the platform, because platforms that are browser-only/PWAs I end up not using on my phone because it never works right for me. And if I don't use them on my phone, I don't use them at all. So for me the main advantage of beehaw on lemmy is being able to use apps like Eternity, Jerboa, and a host of other options to browse and participate in it.
