Uhh, X11 applications work in a Wayland environment. It's no different than how X11 applications work on Quartz, DWM, or any other non-X11 environment.
So it's not like these things are going to break anytime soon...

2) X apps work on Wayland, Quartz, etc. because there are X servers foe those environments, Xwayland is currently the only maintained X server; it too will eventually go away (especially when the toolkit maintainers drop X support altogether).
Just googling to check that claim. As a random example: xorg-server in Arch was last updated on 12/19/22. Six days ago.
Wayland proponents are so aggressive like this. You want to deny that anyone is still interested in X. Maybe it won't have dramatic changes. But people will be patching it for years.
