Like it or not, we are at the end of the IPV4 road
I think that's where you missed it. We are not. The truth is that the
end of the IPv4 road is in sight; how far away we don't really know, as
looking through the NAT binoculars does not seem to make it closer. How
fast we will be there we don't know either, as the Ferrari we were
driving 3 years ago has run out of gas and we're now traveling in a much
slower bus.
Anything that comes out of rearchitecting the
Internet will be at least another 10 year process.
If it's designed as a protocol, likely. If it's designed as a product
with a migration roadmap, not necessarily so. The very flaw in IPv6 is
that it's never been designed as a product that needs to be adopted.
