Matt,
I suppose that nic-se remove the glues that are not longer needed
in ALL cases, don't you?
I agree with all the arguments you have posted in this thread, about
this topic and I would even write a "MUST" for your second "MAY".
3.4.2-[3], updated to cover strictly needed glue:
Name servers MUST be registered with valid IPv4 or IPv6 address when "glue
record" is stricly needed for delegation of a domain from the TLD. The
address MUST be removed when no longer needed for strict "glue record".
