good writing of this draft.

I am interested the following text in section 3:
"   2.  The DNS packet header is not signed.  This means that a "status:
       NXDOMAIN" can not be trusted.  In fact the entire header may be
       forged, including the AD bit (AD stands for Authentic Data, see
       RFC 3655 [RFC3655]), which may give some food for thought;
"
so if the resolver is attacked, such as hacking the "status" field or the whole header, what will happen?

Is this on anyone's radar?   What are your thoughts about it?
