Go ahead; I can't work on this at the moment, anyway. I would also be
confident that a mere replacement of 4.1 with 5.1 should be easy, and
I see no reason to keep the 4.1 version.

Perhaps makeunicodedata should list *why* certain old versions remain
supported; for 3.2, the use case is IDNA.

Martin
