> KDE on Wayland is currently broken on FreeBSD.

Is for me too on Linux. On both a variety of Intel and Nvidia GPUs. On a variety of distros. And everytime I ask around, I'm told it works for others, so it must be me. Everytime forcing X11 solves all my problems.

To be honest, last time I tried KDE on Wayland was a year ago, so perhaps it works now. Then again, so many years have passed where it turned out it didn't, that I'm not particularly keen to try.

It's arguable whether sway is "simple". Last I remember it clocked in at ~50k lines of C excluding wlroots.

Some X window managers are a few hundred lines.

FWIW, i3 is in the same ballpark, maybe a bit less if I am not mistaken.

Sounds like functionality that can be turned into a common library.

It is. Sway is based on WLRoots which you can easily import and build a new window manager on with minimal code.

Most of the wayland fud is either seriously out of date, mistaken, or malicious.
