It appears that Sam Varshavchik  <mrsam(_at_)courier-mta(_dot_)com> said:
MXes which do not announce their limits are going to dominate for some time.  
So, I still need to do this for the foreseeable time. So, what does this  
SMTP extension buy me? The only thing I can think of: not duplicating  
messages when I don't need to.

But the thing is: I don't recall anyone raising this to me, as a problem.  
This is not on my radar screen as a problem that wants to be solved.

I wouldn't think that your users would be very interested, but bulk mailers are 
desperate for
any hints about how much mail they can stuff at people without getting blocked 
or rate limited.
