It is still young and underdeveloped.
It is advertised to be simpler, but I don't understand any of this words thrown in this thread. And I don't care. Pulseaudio and pipewire is still making me troubles, even thou alsa worked without issues for me.
Point it, make it clear and stable and we will come. Until than we will use the beast we know. It os mich easier when there are no options, but Wayland is fighting something that exists and it takes time and effort.
Another problem is they pushed it to early and people got burned. Until I start seeing "I switched to Wayland in one command and everything works" I (as a user) will not touch it (unles my distro decides to drop X).
