Hopefully we will have a compatible migration path to IPv6 before that

The current version of 2005-1 is focused on transition activity.  To
provide a way for IPv4 networks using PI space today to begin using
IPv6 without fundamentally changing the way the operate.  With that goal 
in mind referencing IPv4 policy makes sense and seems to be
generally supported.  It was alot less controversial than any of the
IPv6 only ideas that were suggested.  It also represents a known metric
that we have alot of operational experience with.

I do think we need an IPv6 only PI policy at some point.  Despite many
attempts so far there is still alot of disagreement on how that should
