I know, see commit 1110d14.  But I was talking about
region-history-mode, not vc-region-history.  By placing that mode in
vc.el, we now require _every_ backend to implement this mode, which
doesn't make a lot of sense to me, and you can see in that commit what
that causes for backends that do want to implement region-history.
