Defining an "outbound MTA" would be useful, I guess.

The paper isn't discussing particular proposals, but you seem to be saying 
that it should. It's discussing certain desirable properties of proposals. 
Perhaps you're looking for more detail, or something closer to an actual 
solution.

If you want to say that a desirable proposal would be scalable, then that's 
fine. If you want to say that SPF doesn't scale for a particular reason, 
then that's outside the scope of this proposal.
