I know there have been more than two errata versions of httpd for RHEL 3,
but I only see two in the CentOS updates repo.

Yum-utils has repoclosure.

I would assume that any issues of that nature would come out in QA.

Again, if you run the repository, you get to decide on the changes. One
approach would be to create multiple repos at different stages (using
hardlinks as needed to reduce disk space). OTOH, I personally can't see a
need for more than "testing" and "stable" repos. If a machine falls out
of these two categories for any reason, it probably needs to be handled
more hands on anyway, and would get the needed exclusions in the config
