Coming into this from the outside, the issues are interesting.

I originally thought RRTYPEs are scarce, since all the ones I was
aware of are less than 256.  But it turns out that RRTYPEs are 16 bit
integers, and we've only consumed about 110 of them in ~25 years; we
have about 15,000 years' supply of them.  So they can be handed out
rather generously.

There actually is a standard for allocating RRTYPEs, which is RFC 6195
(section 3.1).  RRTYPEs are to be handed out rather freely.

Obsoleted by RFC 6895 but not too much change.

Thanks,
Donald
