[CentOS] when is the o.s. considered to be at a certain minor version? Or, is it safe to apply only certain package updates from the next release version?

What's not to agree with in that? It may be incomplete, but not incorrect.

Would you agree with "Minor versions are snapshots in time when all of 
the latest updates, and a batch of new ones, are merged into a new base 
repo, the updates repo is emptied, and new installation media are 
generated"?
