"That i'm aware of" doesn't count for anything in the security realm. If 
this document intends to be standards track the default security posture 
is that everything needs authentication. Good luck getting it through 
the IESG handwaving the problem away. At least with mail a little 
normative texts fixes the problem. That won't be the case for http.
