Possibly we should just remove the `ScopedDbgInfoFormatSetter` if everything's already going to have been auto-upgraded (or in the right format already)? OTOH, leaving it behind for another round of clean up will make it more likely we remember to clean up the `TODO` just below. So nothing to do here really, just checking our thoughts align.
