The reality is that people are telling the vendor 'I need X NOW, don't
bother with slowing down to make IPv6 work while you are at it'. Since the
list of X is never ending, nobody ever gets time to go back and add IPv6. If
you expect IPv6 in your products, you have to put money on the table.
Expecting that a vendor will do something that you are telling them not to
by your procurement habits, is really silly.

No, the ops community does not use everything that the IETF turns out. How
many people still use SLIP, RIP, EGP, SMTP over X.25, IP over ARCNET,
FDDI-mib, ...??? The IETF needs operational input about what is really
useful, and that has to come from people that are running networks.

There are vast differences in how enterprise networks are run today than
they were 10 years ago, and in both cases they are different than how
consumer networks are run. Again, this group is composed of professional
network managers, and they want explicit knobs to manage things. Other
environments don't care about those knobs and shouldn't be required to
understand and tweak them. Both are valid and need to operate independently
of the other.

The EU talks a lot, but outside of the 6net/6diss projects has not really
put much money behind it, that I am aware of. Even those efforts were more
about documenting what was operationally possible at the time than they were
about defining requirements.
