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.
So what is the name the new GNOME that supports X11?
Edit: I appreciate the alternative desktops, and they are a great reminder (feel free to keep them coming.)
My point was that open source projects tend to fork every time a less than popular decision is made. Often, removing support for something is seen as a less popular decision. I anticipate GNOME will fork over this. I have no inside knowledge and will not be leading the charge.
