[CentOS] Admins supporting both RHEL and CentOS

With a few exceptions, I see most admins treat CentOS as a single
rolling release and rely on the ABI commitment assuming things
just work between point releases. On the other hand I see the
opposite with RHEL where admins constrain installations to the
point release.

What is the case with users on this list who support both?
