Given that there has already been a vigorous effort to demand much more 
stringent (security-related) efforts in the operation of MTAs, it's 
certainly worth considering application of that demand to this revision 
effort.

The question should be what the driving criteria are.  The follow-on 
question will be how to apply them, of course.

Over the last week, I've found myself increasingly thinking that an 
effort to simplify and focus the document, as much as possible, would be 
especially helpful, notably distinguishing more general email 'systems' 
discussion from the specific transfer functionality that is SMTP's domain.
