Well yes, but not really as not all desktops agree on and implement various wayland protocols and other features like the system tray, server side decorations, etc, etc. Quite a number of apps don’t work everywhere or appear broken depending on their environment. I’ve seen it happen live in a couple of youtube videos. People trying linux and having a problem that only exists on the desktop environment they were using.
But I agree with the sentiment. Better than before.
Seems like a really big release. I’ve never used it, but I appreciate that they exist.
