There's been the proposal for Fedora 43 to go Wayland-only GNOME in advance of GNOME 50 planning to drop its X11 session support. Though there has been some upstream discussion in GNOME about potentially moving the X11 session removal to GNOME 49 instead. One of the items still being discussed is on retaining support for the GDM display manager to be able to support (non-GNOME) X11 desktop sessions still rather than forcing X11 desktop users to rely on a GDM alternative.
Fedora 43 will be shipping this autumn with GNOME 49 and is now cleared to only ship with Wayland support.
At today's Fedora Engineering and Steering Committee meeting they approved the change to go Wayland-only for GNOME with removing the X11 packages.
To be clear, XWayland support is still sticking around for being able to run X11 clients from within the GNOME Wayland session.
