My WM is i3. I know sway exists, but last time I tried it was sufficiently different from i3 to be annoying.
I think overall the problem with Wayland is that there is no user facing improvement over X that I know of.
I have no doubt it's more modern, better engineered, or whatelse. But in the end, the days of fiddling endlessly with your xorg.conf are over, and X _just works_ out of the box on any distro / device.
All Wayland bring me is a switch of WM, and some bugs when screensharing, for no visible benefit.
The only hope of value add I can see with Wayland would be per-monitor DPI. But last I checked, it was hackish at best.
* Have they posted what is blocking them? Besides a lack of hands on keyboards?
I am trying to narrow down exactly what the issues are. Too much of the conversation is 'something' is broken in Wayland because of 'something'.
