It’s in the implementation limits for Acrobat, not in the normative section.

Great. That used to be 1 bp so now it's more. As it happens, we do have a check for this in context so we can adapt it ... but, as this 3 bp is kind of arbitrary and because 3 bp becomes a float and thereby ends up slightly less than the integer 3 we can best play safe and revert to the usual tex joke, so i now set the minumum to \luaexpr{math.pi}\onebasepoint which then gives: /MediaBox [ 0 0 3.141539539 3.141539539 ] because after all, any rediculous minimum will do and that way a user can still figure out that it's a value set by context.
