CentOS should do whatever RHEL/Upstream does.

Period.


Why the change now? It really does matter, a lot, to those of us who need
to do compliance testing/security checks, etc. all based on "version"
number. I know there is no such thing in practice because of all the
non-sequential updates that happen, but there's a shit-ton of work that we
have to do for each new release, and we have depended in the past on the
versions matching the RHEL ones. Now, they don't, and that's wrong.


It seems like a minor thing, but in real-world practice it is most
definitely not.
