Which feature?

With the draft, when queried with an OPT RR, you either have to answer
with an OPT RR, or produce a FORMERR.  This answer wouldn't be allowed
anymore:

; <<>> DiG 9.7.3 <<>> @ns3.schlund.de. quantenblog.net. +dnssec +norecurse
; (1 server found)
;; global options: +cmd

This definitely looks like an error in the draft to me.
