I believe this would be a valuable change.  I know a lot of other users
want this features as well.  However, I think it needs to be opt-in,
since there are some cases where you want `git fetch` to specifically
fetch only certain objects or don't want to modify the refs. For
example, I know some server-side implementations use `git fetch`
internally and require refs to be updated in a special way, and they
would not appreciate extra refs appearing.
