Enabling minimal-responses on an authoritative server will break any other server with a stub zone declaration with this authoritative server listed as master. The implementation of stub zones assumes that an SOA query will retrieve all of the required information (SOA, NS, and supporting A/AAAA records) to successfully insert the zone apex into the cache.
