So, while this seems better than an actual diff for the sqlite case, it
still doesn't solve what (at least to me) has been the fundamental
question with doing diffs like this --

When does it make sense to use a diff vs when does it make sense to grab
the "full" file?  And that was the problem that we used to have with the
maintaining of metadata diffs with yup[1]
