Except people do notice the change, as a workaround many still rely on certain aspects of X via Xwayland in an attempt to keep things running. Even Steam doesn’t support Wayland.
Fact is, Wayland’s been in development for a good decade or more, it’s still in a state of perpetual beta, and that’s a situation that isn’t likely to change any time soon.
Xwayland makes use of legacy features of X. If we were to compleately drop all aspects of X tomorrow, the Linux desktop would essentially compleately break and become unusable.
The fact is, at this point in time after 10 years or more of development, Wayland is still very much in a state of perpetual beta. At this point in time, and for the foreseeable future, Wayland involves compromises that make it unsuitable for many users.
Hopefully things improve in time, the problem is development is progressing at snails pace.
