I'll bet if we had a single IPv4 over IPv6 solution which had
a clear operating cost savings over Dual-Stack, and also over
IPv4-only+CGN, that we'd be at universal deployment of IPv6
already.
Since we are engaged in a counterfactual guessing / betting
game, I'd bet that would be true had we defined such a solution
a decade ago, that it were realistic, and that we had stuck to
it. At this stage, the cartoon is relevant -- not only would we
be likely to add another method to the list when existing ones
already have their advocates, but dropping two or three would
not be enough to make a significant difference.
