Or we could just ask that zone adminstrators and in particular gTLD
registry operators actually do what is required of them for operational
stability.  I don't see "except section 4 or 4.2 or 4.2.2 or 4.2.2
paragraph 3".  I do see a exception to restrict the use of hypens
in labels.

1. Standards Compliance

1.1. DNS. Registry Operator shall comply with relevant existing
     RFCs and those published in the future by the Internet Engineering
     Task Force (IETF), including all successor standards, modifications
     or additions thereto relating to the DNS and name server
     operations including without limitation RFCs 1034, 1035, 1123,
     1982, 2181, 2182, 2671, 3226, 3596, 3597, 4343, and 5966. DNS
     labels may only include hyphens in the third and fourth position
     if they represent valid IDNs (as specified above) in their
     ASCII encoding (e.g., “xn--ndk061n”).

RFC 1034, Section 4.2.2. Administrative considerations

"As the last installation step, the delegation NS RRs and glue RRs
necessary to make the delegation effective should be added to the parent
zone.  The administrators of both zones should insure that the NS and
glue RRs which mark both sides of the cut are consistent and remain so."
