That is not what the decision said. The point was that the DHCP WG was not
going to decide for you what was necessary or appropriate to carry forward.
Rather than add baggage that nobody actually uses, there is nothing until
someone says 'I need that'. Never mind that DHCP wasn't defined when the
IPng work started, and wasn't in widespread use yet when DHCPv6 was being
started ...

Yes people expect 1:1 functionality, but how many of them are stepping up to
the table with $$$ to make that happen... In the US, it is only the DoD. In
the ISP space, most of it comes from Japan. If you are not finding what you
want, put money in front of a vendor and see what happens... ;)
