Note xwayland isn't included in that. Also some read deprecation as already replaced which isn't necessarily the same thing.
Being Asahi is not only brand new but not even near a first stable release the amount of surprise about the lack of xorg focus seems as silly as those that act like wayland reached parity 2 years ago
I do wonder if that isn't a solution. Couldn't they just ship rootful xwayland as the officially supported X server on Asahi, thereby being able to drop X.org without trashing people's setups?
Edit: This is a suggestion, not a "well why didn't they just do this".
XWayland is just an X server on top of Wayland. You could use it to run your whole desktop, but it's not the best use for it. It's really just great at running legacy applications without a Wayland version (especially old games and such).
