Regardless of the opinion of the IETF (or more accurately certain participants in
the IETF, since the IETF never made a coordinated statement of any sort of
WG conclusion that I was off base on that), those were the facts on the ground.

IETF had allocated 2000::/3 to IANA to dole out as Unicast address space.

IETF had provided recommendations about how it was to be managed, but whether
IETF (or more accurately certain IETF participants) recognized the limits of their ability
to enforce those recommendations, the RIRs were, in fact, free to make policy regarding
the administration of those address spaces (individually for space allocated to them by
IANA and collectively (via the ASO AC) for how IANA would manage allocations to RIRs).

That’s been the structure of address policy for v4, v6, and ASNs since IANA first started
delegating address management to RIRs.

You keep saying this as if there was some huge expense to IPv6. I admit I don’t know your specific network, but it’s pretty hard to fathom that at this point.

Then there’s probably a limit to the amount of time that $job[0] will remain able to communicate with the full internet.

You quoted 25% and 3% numbers earlier, I don’t know what your source is, but from Google, Facebook, Netflix, and Akamai, it looks like something close to 50% of all internet traffic in North America is IPv6. More than 50% of all mobile traffic in that same area. World wide the numbers drop some, but they are continuing to rise.

That’s been true to some extent since the early days of IPv6 development. There was always going to come some time when the majority of the internet was going to decide that supporting IPv4 wasn’t worth the cost or hassle any more and at that point, you’d have IPv4 islands in an IPv6 ocean. That fits the definition of balkanization[1] for some.
