Recent announcements that both GNOME and KDE Plasma may ship in Fedora 40 without an X11 session (so that way it doesn't need to be supported in the next RHEL).
It probably won't be a (big) problem for the Talos II, since I have a WX7100 GPU. It *may* be a problem for my Blackbird since I explicitly run that strictly on the BMC framebuffer as a low-end test.
