Hard to say how "deliberate" it was, at this remove of time.

I do see an argument against reclassifying macaddr[8] into
TYPCATEGORY_NETWORK now: we generally expect that if a
category has a preferred type, any member type of the category
can be cast to that preferred type.  (The fact that OID is
marked preferred breaks that rule, but it holds pretty well
otherwise.)  I think this is why type interval has its own
category rather than being within TYPCATEGORY_DATETIME.
