As one of the authors of the IPng Requirements (RFC 1726), I'm going to risk
piping up here.  The requirements in RFC 1726 were for an IPv4 replacement
that scaled -- if you read RFC 1726 (and I just went back and did) it is
carefully
only requiring what we'd already achieved in IPv4 -- with the exception of
saying
we'd like something that configured better than DHCP.

So Tony's closer to right.  We were so scared when we wrote that document
that
we only had a few years that we wrote remarkably conservative requirements.
(I'd actually pushed to be more ambitious and got shot down).
