@Lyude normally there is https://wayland.app/ but it lists "no desktop" for "Pointer warp", but that's probably because nobody updated it π
I do think we can document it, and maybe have something like "profiles" per use case, so I don't think it's necessarily a bad idea to make it easier to find what's supported across the desktop.
But I think it's mostly a documentation problem, because app developers need their own documentation (like https://wayland.app)
