Well, thanks.

The only way to really tell is to check the changelogs for all packages and
diff that with a RHEL system. Assuming the changelogs are modified (which
AFAICT they are). rpm -qip --changelog packagename.rpm. Iterate over 1,494
packages. :-)
I used to provide lots of detail in my changelog entries (see the PostgreSQL
spec files for the previous versions of PostgreSQL; the changelog
historically has been truncated at each major version to keep the size down)
so that people could fathom what I had changed from release to release.
Tracking these sorts of changes either needs to be fully automated (Johnny is
so right that it takes time to do this) or someone needs to step up to the
plate to chug through the changelogs, spec files, and patchsets. A specfile
changelog tracker might be nice; if the specfiles are in CVS (or other
revision control system) a committers list could be set up that would e-mail
that list on each CVS commit (lots of projects, including PostgreSQL, do
this). Then it's up to someone to digest this for public consumption. I get
these sorts of e-mails from the PG rpmfoundry CVS server (while not terribly
active there anymore, I still track it and provide advice when asked).
The practice of segregating the repo into a CentOS base, the addons, and
centosplus is great; unfortunately there are changes that are in the base
that really must be in the base. Such is life.
As far as the 'substantial' part of things, the centosplus repo is what I'm
thinking about, along with the building into the ISO form, setting up the
install, etc.
