Re: [v6ops] About Req for Comments - "Transition to IPv6"

Eliminating IPv4 implies eliminating the use of IPv4.

Eliminating the *use* of IPv4 does not imply eliminating IPv4.

I don't see any real problem here.  Maybe they *want* the vagueness (i.e.
absence of over-specificity) to have some grey area to support NAT64/DNS64
(or maybe even 464xlat).
