Re: Confirmation to advance: draft-ietf-6man-ipv6only-flag-05

I like this option below gives flexibility to the managed networks or use
cases where the desktops are not yet ready for IPv6 only and they can flip
the switch when the time is right in the future.

***From B Zeeb***
Given as of the last draft there is an option to disable processing
despite implementing, OS vendors can implement the draft and do what
they think suits their users.   Even more so they might leave the
default to “off” for now as an “advanced option to turn on” and
with a major OS update, once the world has moved on, flip the switch in
the future.
