@peppe Well, #dwm is a window manager. Then there's #dwl, which is a #wayland #compositor, trying to do "functionally the same" as dwm. My point is, it has to implement a lot more stuff to do so.
My favorite window manager is #fvwm (or now #fvwm3), and as far as I know, its main developer was looking into wayland and currently doesn't have any concrete plans to work on that ... and I can perfectly understand.
