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.
It is more like saying we should drop hydrogen cars because they are a fundamentally flawed concept.
Except you can't explain any fundamental flaws with wayland that don't also apply to X11.
We will drop electric cars because hydrogen cars are fundamentally superior.
Hydrogen ist a nightmare to store and transport and 90% of the ways it can be produced for the foreseeable future are very polluting.
That's just propaganda from BEV companies. They just saying that so people won't realize that hydrogen solves many of the problems of electric cars.
