connectivity sufficiently useful to most, or any,
users that there is a real demand for it.
Yes.
For years IPv6 promotion has been along the lines of the impending
disaster of running out of IPv4 addresses, coupled with IPv6 being
something like the next version of "the Internet" with boundless address
space. I do not recall these efforts at promotion explicitly stating
the truth that the IPv6 Internet is a separate Internet from the IPv4
Internet.
Yes.
Finally, here are two quotes from discussions on the IRTF Routing
Research Group list regarding IPv6 adoption:

Just like with NAT. The IETF would rather stick its head in the
ground - thereby ensuring that whatever happens, it will be done
by individual actors, in an incoherent way.
Like the Bourbons, the IETF has learned nothing, and forgotten
nothing.
The IETF never learns from its mistakes. It hides its lack of
imagination by mitigating the awkward questions. It's a natural
feeling; nobody likes to admit failure.
