That would be a good way of damaging IETF productivity for a few hours. And for what? Moving away from the mainstream coexistence mechanism (dual stack), to a mechanism known to be intrinsically defective (NAT). I don't see the point. IPv6-only is a *very* long term goal for campus/enterprise networks, which the IETF network resembles. Our realistic goal today is for enterprise networks to achieve dual-stack coexistence, and most enterprise network are nowhere near that point yet. There is no point in leading from so far out in front that nobody else can see you.
