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.
Wayland takes a conservative approach to feature requests. Disabling screen tearing goes against their zero screen tearing goal. Other features, such as X11’s remote capabilities, are unnecessary baggage and a security risk. Yes, people who use the remote capabilities kicked and screamed, but they now have Waypipe. Turns out building that into Wayland itself was unnecessary after all, a 3rd-party app made it happen. Their primary goal is to not end up like the mess that is X11.
