Yes, the draft says the primary has to agree to send them to the secondary and the secondary has to agree to accept them (administratively). This prevents old authority servers from having to deal with them. The position of not having them signed is a consequence of not having them returned in a query. If you can’t see them in a query, you can’t do NSEC/NSEC3/NSEC5 next record semantics so we skip them. By simply making them returned in a query, we can avoid most of your objections. Mark Andrews suggested they not be returned in a query in a hallway discussion and I’m happy to change if that’s the preferred approach. Thanks for the feedback!
