For CVS I could argue that CVS/Base/<file> should/could be used instead,
but it probablt makes more sense to do as you did.
[ wondering about interaction between that new thing and the multiple-backend
  support.  What if RCS' version 1.32 is not the same as CVS' version 1.32 ? ]

I don't see the need for removal when doing the revert.  90% of the
times I use vc-revert-buffer it is to create a new version with only
some of the diffs (in order to commit some of the local changes),
in which case, I'd much rater keep the version-backup.

Also, not removing in the case of revert would allow the use of revert-file
in vc-transfer-file.
