Well, I wouldn't say that. Let's augment instead:

1. IPv4
2. Dual stack
3. IPv6

What we have discovered is that step 3 won't be reached anytime soon 
because too many people are stuck at 1.

So to give people who want to go to 3 for their access, we need them to be 
able to realise 2 by means of v4aaS.

So for me the plan is still "interop between IPv4 and IPv6" but it might 
not be dual stack everywhere, instead it's v4aaS. Because long tail is 
long.
