Wayland was released 12 years ago. Should we keep waiting? The Linux desktop already lost. You can attribute it to a lot of things, but it's nothing to do with WSL.

Windows users win. The Linux desktop loses.
The Linux desktop has now been made even more irrelevant for new developers as Microsoft merges it with a Windows desktop.
