YEs, I agree.  That text is sufficient.

As a side note, I would be doubtful naming an IPv6-only access network
something that uses IPv4 as well (464xlat, dns64).  I would rather call
it a "mostly" IPv6 access network, with a little of IPv4 however.

This is just a matter of terminology.

Also, since we last discussed we went trying eliminate the IPv4 stack
from a linux kernel.  That is not possible.  So any 'pure' IPv6 machine
that would connect to an IPv6-only access network is just a speculation
at this point, years away from any deployment.
