GNOME lifecycles in RHEL differ from other, leading-edge distributions. GNOME rebases aren't just simple API/ABI compatible minor updates, and things can break in doing so, therefore RHEL engineering wants to do them sparingly. Granted with GNOME 3.x there were quite a few rebases in RHEL 7 and RHEL 8 to fix issues and growing pains. Feature and fix backports are the preferred method for updating GNOME in RHEL, rather than complete rebases. The Xorg Server has been deprecated in RHEL, but exists in both RHEL 8 and RHEL 9 and will be maintained in those distributions for the entirety of their lifespans. It will be removed in some future version of RHEL. X11 support is provided by XWayland.
