This is vaguely a double-edged sword. Yes, more code duplication across disparate projects - but that also allows people who _really care_ (such as the xfce team) to roll up their sleeves and do more. Any WM will only ever be as good as the X11 baseline, Wayland servers have the opportunity to compete on this front.

Although I'm probably permanently stuck with the Niri workflow, I am looking forward to seeing what the xfce developers come up with.
