yes long term support for every stable release things can still change between the releases RHEL 9 is supported until 2032, with the right support contract you might get even more years, idk. so you have another ~8 years with Xorg on RHEL and since RHEL made Wayland the default in RHEL8 (released mid 2019) it is clear for 3+ years that you _slowly_ have to start planing migrating to Wayland. Which means customer have around 10 years time to slowly plan and execute the migration.
