Such testing is not mission creep.  The test is simply based upon
SMTP being the focus of ADSP assertions.

But SMTP IS NOT, and CANNOT BE the focus of ADSP assertions, simply
because a message may be gatewayed in and out of SMTP umpteen times
during its journey from original sender to ultimate recipient.

Messages containing addresses unrelated to SMTP will always
potentially conflict with ADSP. ...

NOT TRUE. Messages containing addresses unrelated to the DNS system will  
always potentially conflict with ADSP. SMTP messages are but a subset of  
those.

The true "focus of ADSP assertions" is "all those protocols which
rely upon DSN as a part off their addressing mechanisms".

There is no assurance that an undefined protocol will use DNS, since
there are already such protocols available.  The draft should indicate
limitations imposed when adopting ADSP.

Exactly. And the limitation to be imposed should refer to "all those  
protocols which used DNS-based addressing mechanisms", which is more than  
just the one protocol SMTP.

Moreover, limiting it to SMTP is unimplementable. What test do your  
propose? That is was received via SMTP? That is was originated by SMTP?  
That is was passed via SMTP at every stage in its journey?
