Which brings up the other problem that Wayland introduced, that instead of one incredibly old inscrutable software stack doing these things there are now five (and counting!) new and insufficiently tested software stacks doing these things in slightly different ways.

It would have been nice if KDE and Valve could (would?) work together to reimplement KWin's features on top of wlroots. That would have basically made Gnome the sole holdout, and I imagine they'd eventually have switched to the extended wlroots as well, or at least forked it.

There's also EFL and one other I'm forgetting at the moment, but yeah.
