As someone who attended the interim IPv6 IETF meeting in Montreal in
October 2008 where much of this was discussed, I can say that my
motivation was more about enabling IPv6-only networks to be deployed
without having to pay an IPv4 deployment tax. I felt it was important
for an organization to be able to move forward and deploy an all IPv6
network if it wanted, and only worry about the translation to IPv4 at
the edge, to the extent practical, similar to most (non-residential,
and I suppose non-colo) IPv4 deployments today.
You seem to be drawing an analogy between IPv6 and IPX. I suppose
only time will tell.
