I agree. I see a lot of ISPs, and especially those in mobile and
cable, forging ahead with real near term IPv6 plans and deployments.

These folks do not want to care how things work.  The fact that IPv6 makes them have to care is probably the worst failing of IPv6.

Right, i don't see that end users need to care in many cases.  We can
talk about IT managers who manage technology, but i am more interested
in mobile and broadband networks where IPv6 can be deployed in the
mobile handsets and people's homes without them knowing or caring, the
service just works.  Most people don't know about IPv4, and they don't
need to know about IPv6.

I am seeing the most resistance today, in the end user devices (CPE, UE ...).

Case and point of no follow-up,

Which leaves well meaning people attempting to find, universally
described as non-ideal, technology solutions to deploy IPv6 over
IPv4-only CPE / UE

The network edge has always been hard to plan for, but seriously, this
train wreck has been traveling at 1 km/h for 10 years now.  And, to
the credit of some in the CPE / UE markers, they are covered (Nokia,
Dlink, ...) ...and critically, others ...not so much.  I hope those
early adopters get some spoils from their visionary work.
