I’ve switched to Wayland a few weeks ago on my new laptop and it took me quite a while to figure things out, but mostly it’s functionally complete for me compared to X.

The main difference is mostly that it’s really complicated to achieve simple things in Wayland, like nesting Wayland servers or remoting Wayland sessions, but that’s mostly because there aren’t convenient, ready-made, universal solutions to do these things in Wayland yet - which, I agree, after 16 years of existence of Wayland, is utterly stupid.

But after working on it for some time, it’s all there for me. The only thing that I really miss is a decent RDP server that works in Sway.
