How is range 3 different from any random type like TXT?
Random types like TXT can't exist at a delegation point.
I see this in RFC 2181 sec 6.1:
Other than the DNSSEC cases mentioned immediately below, servers
should ignore data other than NS records, and necessary A records to
locate the servers listed in the NS records, that may happen to be
configured in a zone at a zone cut.
That sounds like don't return them, not forbid them.
