Missing xorg-xwayland make dependency makes kwin use deprecated -listen
https://invent.kde.org/plasma/kwin/-/merge_requests/739
xorg-xwayland /usr/lib/pkgconfig/xwayland.pc
Current package contents:
[0] % grep -R XWAYLAND # alias of grep --color
usr/include/kwin/config-kwin.h:#define HAVE_XWAYLAND_LISTENFD 0
Also opened an upstream issue about this because it does not seem right to be able to miss this.
