Say what? That's not my recollection at all. But this isn't the
Internet-History list, so I'll move on.

That's a complex question, and it depends in part on how many other
namespaces there are.

Well, that is certainly true.

That has minuses as well as pluses, though. A big one is that if IPv6 is just
IPv4 with a few more bits of address, then you sort of limit the capability,
and therefore the benefits, of IPv6. No architectural changes -> no
new/additional capabilities.

A powerful observation, one we should all remember...
