I am basically in the same boat, interacting with RHEL mostly because some of our customers insist on using it. It is already a giant pain with its tiny number of packages and the whole license tool struggles. At least so far we could build our internal tooling and the software we build for our customers on simple Centos or Alma Docker containers and use those for test systems as well. But now dealing with RHEL at all suddenly became an order of magnitude more painful, especially as others will also reduce support for it in their third party software we use.
