Future Nitrophones

I have heard that when Android v16 comes out, that Google is withdrawing binaries from AOSP availability. (I think that’s correct.) My understanding is that this will make it incredibly difficult for Devs (like GrapheneOS) to continue. Is this correct? When Google releases their Pixel 10 Pro XL; will Nitrokey still be able to offer a “Nitrophone” based on that hardware; with GrapheneOS pre-installed??
