No headless RDP solution is pretty unforgiveable in 2026 - right now I use Nomachine and indeed it requires X11. Why wouldn't Wayland have a solution for this? It is not a niche usecase. It is like, a headline, completely mainstream use-case.
Blind spot that comes from incompetence and arrogance. See https://lwn.net/Articles/553415/ for example and remember famous words of Daniel Stone that brought the need for remote work to - merely - launch xeyes.
Thus, that particular comment (https://lwn.net/Articles/555124/) was prophetic:
"With that sort of attitude, I have no confidence that remote Wayland will ever work properly. Clearly Daniel just has a laptop and does all his work on it, and damn everyone who uses more than one machine for anything."
