=> That's fine with me. In that scenario the question of the flow label
would not come up though.

=> I think you could think of analogous situations where the requirement
would not apply and therefore the IESG would not hold you responsible. For
instance, suppose we're updating the NAT RFC or RFC 1918. I'm pretty sure
the IESG would not require you to reserve a block of IPv6 addresses for
IPv6-IPv6 NATs. This is a similar case.

=> I was only referring to IPv6-IPv6 scenarios, clearly there is merit in
the IPv4-IPv6 cases.
