RHEL itself is deprecated for desktop/workstation use. I last used RHEL in that capacity 10 years ago and even then it was apparent that this was a niche it wasn't well suited for.
The target audience for RHEL desktop/workstation use is government employees. Those people are not supposed to use the computer beyond a narrow scope of tasks. Creativity, self-responsibility, individuality and out-of-the-box thinking is discouraged. Wayland is perfectly suited for that.
Fedora defaulted to Wayland quite a while ago. But Fedora doesn’t necessarily always follow Red Hat. RHEL deprecated and removed btrfs support, while Fedora now uses it by default.
It wouldn't really surprise me if Fedora followed suite soon, but I have no specific information about that. Hopefully OpenSUSE Tumbleweed keeps X, I haven't heard any indication to the contrary.
