I believe Paul's point is: What makes you so sure that people with
limited routing slots, will choose to carry those new fangled v6
things that only geeks are using, versus turning off v6 in order to
carry more v4 routes?  There isn't a magical routing table separation
inside the box.  Providers know who they can reach on v4, they know
there is content on v4 and that they will have less complaints and
more customers working if they choose v4 over v6.  Another thing that
could happen is that folks move to filter on /23 or shorter, instead
of /24.  It's hard to imagine that today, but that may be more
palatable than dropping entire regions.

In all of this, I have not seen a push for better aggregation - so
here is a nudge.. if you see your company on the list, go ask why and
see what can be done to aggregate.
