Yes, there are definitely some valid concerns I share regarding
deaggregation, and the possibility that action taken to reduce the impact
of IPv4 exhaustion may slow down IPv6 adoption. However, on balance I
think we can address most of the deaggregation concerns with the
restrictions in 2008-2, and I think it will do more good (in reducing
transition costs) than harm (in extending the transition over a longer
But in addition to (re)debating those points, I'd love to hear any further
feedback on how folks think we should revise 2008-2. There will be a
consensus call on it at L.A., and I'd like to have the best possible
proposal on the table when we get to that point.
