Makes total sense to me. I will work on writing something up this week.

I will say the reason this is even a thing we noticed is that we can't
simply drop the changes (or have the be combined with a
'update-metadata' commit) in our process during the rebase, as there
isn't a tool that can 'replay' them like `update-maintainer` does.
