Nothing, except that (1) that approach won't catch refs outside heads and tags (like the ones I have in refs/merge-fixes and refs/hold), and (2) it won't have an early termination optimization I mentioned either.

I don't know how much the early termination optimization matter in practice, though. It would probably depend heavily on where you begin.
