Wayland may not be non-UNIX, but putting everything into the compositor
(including keyboard input) just shifts responsibility to another piece
of software and actually complicates things a bit. I've not done much
digging into the matter but if I understood the structure of Wayland
correctly, you can't take screenshots or other talks-to-display-server
stuff unless the compositor supports it. With so much I/O going through
one thing (the compositor), it's ripe for abuse and security problems.

Of course, that doesn't make Xorg's security problems go away... like
any other set of competing software, you're trading one set of pros/cons
for another.

I've not seen anything about Wayland that convinces me it's hands-down
better.

That plasma dependency sounds weird, though. If you're not using
Wayland, it shouldn't require mesa to support it.
