Yes, I am busy trying to catch up with my backlog (do intend to look at
this more closely) but wanted to say - let's please document what we're
doing here in a comment.

It's my firm conviction that we in mm need to eliminate as many instances
of 'just have to know' or implicit knowledge that is either undocumented or
tricky to find (buried in a commit message from X yrs ago for instance).
