A set of merge requests were opened that would effectively drop X.Org (X11) session support for the GNOME desktop and once that code is removed making it a Wayland-only desktop environment.
Going along with Fedora 40 looking to disable the GNOME X11 session support (and also making KDE Plasma 6 Wayland-only for Fedora), upstream GNOME is evaluating the prospect of disabling and then removing their X11 session support.
Some concerns were raised already how this could impact downstream desktops like Budgie and Pantheon that haven’t yet fully transitioned over to Wayland. In any event we’ll see where the discussions lead but it’s sure looking like 2024 will be the year that GNOME goes Wayland-only.
If they had kept the window manager concept, separating mechanism and policy they would have only needed one implementation for all the mechanisms.
yes, they could have made the implementation from the start, and that is a valid criticism to wayland(i also agree), but we have wlroots now, and they are working very close with KDE(in one of the devs blog they even said about KDE being ported to wlroots in the future), except for gnome, every DE are working together
