Our reflog interfaces are still quite awful, but they have recently
evolved so that we can at least batch-commit reflog entries via our
transaction interfaces. They are still severely lacking though, and I
haven't yet had the time (or motivation) to improve upon this.

I think instead of introducing the proposed interface, we should first
investigate whether we can make the reference transactions more powerful
to allow for all of these use cases.
