I keep a Raspberry Pi on my desktop with plan9front because slow as it is, it's still the fastest way to get a VNC/ssh client going, but I don't think Wayland would be much of an improvement (although anything is better than Rio at this point).

The problem here is that most of the plan9 community is too set in their ways to counter the dogmas around, say, Acme and three-button mouse usage (just to use an example that is UI-related but not strictly about the environment) or has moved on.

Mind you, plan9front is still being maintained (and fixed, including EFI and 64bit stuff), but people doing UX and graphics seem to be in short supply in that neck of the woods.
