And we're still trying. I spent the last three years in the IRTF RRG
and we still don't have either a consensus approach or a technology
which can be proven to do useful work in even the corner cases. There
are some really clever ideas there with some real promise, but not
enough of them are being built and tried to answer some of the
identified unknowns and lock in on what might work.

I've harped on it before, but if we had a pool of cheap, non-need
based registry-assigned addresses that were explicitly and
intentionally barred from BGP, the combination of all the kiddies
wanting PI and the availability of PI addresses might restore some of
the motivation to develop a tech capable of using them.

In spirit I'm with you 100%. Pragmatically though, the number of folks
who enjoy both development and operations is a lot smaller than the
number who enjoy one or the other.

I can set your mind at ease for the second part. For the former,
you'll have to decide for yourself whether I made an adequate effort
to understand your viewpoint before disagreeing with it.

We should change things exactly as much as experience and a healthy
caution reveals is needed. If you did as a good a job on IPv6 as was
done on IPv4, you can expect as little change as IPv4 underwent. Did
you? And when we think back, just how minor were IPv4's needful
changes like CIDR and NAT?
Yesteryear's best decisions were rarely deluded or misguided.
Following them uncritically today can be.
