It will do all of those things in the right circumstances though. Dual-stacked eyeball ISPs see over 50% of their traffic go via native v6. If they're CGNATing then that corresponds to a substantial drop in the amount of traffic that needs to be CGNATed, and therefore also a corresponding drop in the cost of the hardware needed to do it.
