Section 5.1.4. says:
the response would contain an RCODE of 0 (no error). Otherwise, the response would contain an RCODE of 4 (NXDOMAIN).
It should say:
the response would contain an RCODE of 0 (no error). Otherwise, the response would contain an RCODE of 3 (NXDOMAIN).
In RFC1035 section 4.1.1. it states that an RCODE of 3 is 'Name Error' aka NXDOMAIN. RCODE 4 is "Not Implemented". RFC 7707 incorrectly refers to NXDOMAIN as RCODE 4 instead of RCODE 3.
Here is the output of testing this in Wireshark:
