Afaik it would also support at least the core parts of X11. It would
be declared legacy, and not part of the perpetually supported Wayland
set, but I think it is safe to say it will be supported for quite a while.

IOW, I wouldn't desperately try to support Wayland native at this point.

That can be done if the native api turns out to be stable, Wayland truely
takes over X11, and all distros package it.

Now it is just asking for pain IMHO.
