My point was, if a network continues to grow and eventually does use up 
what it gets (just not at the expected pace) nothing's been wasted, and 
global routing table slots have been conserved.

As I've said a couple times recently, I'm not opposed to / am in favor of 
issuing PI /24s to any multihomed network.  If you're multihomed, your PI 
/24 takes up the same global table routing slot your PA /24 would (less 
space if you had multiple PA /24s from your various providers which 
you'd give up to get PI).

If you're not multihomed, and not big enough to qualify for PI space under 
current guidelines, sorry, you get to keep using PA.  Otherwise the 
routing tables really would explode.
