I really hope it makes the jump to Wayland. I've used XMonad for more than a decade and it's still my favorite WM.
XMonad really let me forget about managing windows---I never have to resize a window or remember where I put a window. XMonad handles the arranging and resizing and floating for me. There's a nice layout for small screens that will zoom your active window[0]. You can cobble your desktop together into whatever makes you happiest: Active corners. ScratchPads. So much in XMonad Contrib[1].
Since I'm not the right person to help with porting to Wayland, I'm giving money via the GitHub sponsorship page[2].
I check in on discourse from time to time: progress looks slow. The person/people they need are hard to come by.
