It should say explicitly "resolvers keep doing $z, there is no change here". Also, for the text about authoritative servers, I agree that changing the SHOULDs from the current standards to MUSTs. Changing this to MUST means that every time a zone changes its SOA TTL or SOA MINIMUM value, the whole chain of NSEC/NSEC3 records need to be updated accordingly immediately. That may be undesirable for a large zone. BIND for example would make such a change incrementally, so there may be a period of time where the NSEC/NSEC3 records still have the TTL of the previous SOA TTL/MINIMUM value. With a SHOULD keyword we can keep this behavior. With a MUST less so, I think. So I am against changing these SHOULDs to MUSTs. Best regards, Matthijs
