The most relevant bit in the current draft is:

   If the DNS query includes DO=1 and the QNAME corresponds to a zone
   that is known by the responder to be signed, a valid RRSIG for the
   RRSets in the answer section MUST be returned.

which does in fact imply that you can leave the RRSIGs out when DO=0
if you read it properly (which I evidently failed to do!) but it's
probably worth saying so explicitly.
