I have to ask .. why?

If you're worried about security updates, Red Hat monitors dozens of channels and backports all security fixes to all supported software, so that's not a problem.

If you're worried about features, Red Hat selectively backports features at customer request, or gives the customers free updates to the new RHEL.

Our customers want to install a particular release of RHEL and have it work and supported for 10 years. They actively don't want random version upgrades (which often remove as many things as they add, as well as causing exciting new bugs).
