And if you think that's a lot of fussing around for a simple result -
it's why 'changesets' were invented:

CVS supports two kinds of changesets:
- CVSNT 2.x and CVS 1.12 both support 'atomic' changesets (what
Subvserion calls 'atomic commits')
- CVSNT 2.x on Linux/Unix/Windows/Mac supports 'user defined' changesets
(what ClearCase calls a 'defect')

I have observed that increasingly the job of managing 'change sets' is
being offloaded into proprietary systems (Jira et al) even when the
'source control' is open.  I'm not a fan of this for several reasons,
but mostly I just think that pragmatically the information about the
relationship between one change and the other belongs in the versioned
repository not in a separate database.

note: it has been observed that if your CVS repository gets cluttered
with 'too many' tags the performance can decrease, which is (one of many
reasons) why in CVSNT 2.x for Linux/Unix/Windows/Mac we put in user
defined changesets.
