Actually, I think most VCS can support it one way or another.

We've had some bug reports about vc-sccs.el in the
not-completely-distant past, so there might still be such people
out there.

But contrary to what the above two statements might lead you to think,
I'm in favor of removing this rollback, because I don't think it's good
enough as it stands.  E.g. I think it should be replaced by an
`uncommit' which would be the opposite of `commit' and should ideally
preserve as much info as possible (e.g. not change the file's contents,
and stash the commit message somewhere so it can be re-used if you
decide to recommit).
