Can we make use of the keyword MAY? This allows I think for text that will not get out of date: Validating resolvers MAY return an insecure response when processing NSEC3 records with iterations larger than 0. Validating resolvers MAY also return SERVFAIL when processing NSEC3 records with iterations larger than 0. This significantly decreases the requirements originally specified in Section 10.3 of [RFC5155]. See the Security Considerations for arguments on how to handle responses with non-zero iteration count. Having text that says "MAY do this at value X" is more quantifiable and IMO a stronger signal that zone publishers really should not use value X. Best regards, Matthijs
