I agree that there isn't a very strong justification for making a
non-trivial change like this.

I would also like to understand why 6962-bis consolidated all the type
indicators into a single one before that work is undone.

Absent a stronger justification and an explanation of why the
consolidation was done in the first place, I favor keeping 6962-bis
as-is.
