> Outside of rare special cases, yes, they will still work using the Xwayland compatibility layer. It does a great job of providing compatibility for most X11 applications

Not on my 4 year old PC. Wayland performs poorly and usually in wonky ways. I tried it for several weeks. Could not stand the odd behaviors and poor performance and went back to X11. And this is an AlienWare PC, cost me $2000 US, the most I've ever paid for a PC. Can't imagine how bad Wayland would be on the lesser PC's/laptops in our home.
