Hi Curtis,

I agree with you and support this to become an IDR WG doc.

Even if ever AS_HOPCOUNT is used to limit specific propagation of just 1 
hop away it already will be very useful.

And and far as additional incentive goes .. proper network design should 
be enough of incentive :). Maybe that goes against $$$$ rule but IMHO it 
goes along the real large scale network design principle (if that even 
still matters these days :-).

Cheers,
R.
