Following the discussion I would say it has been shown that is is possible to
run a registry without the strict requirement of registration with ip
addresses for all name servers (in the registry TLD).

So that appears to be a very good reason to change the "MUST".

Maybe then there should be an addition like "registry must require all
nameserver ip information to enable a healthy DNS system, at least glue records
with are absolutely needed"?
