Now, the nice thing about requirements is that when you read
them into detail, they can be interpreted in both ways.
No. A dual-stack host is NOT a v4-only host. If you read the requirements to
the letter, nothing excludes changes to dual-stack nodes. But I humbly think
the real question is not what the current requirements say.
So, the question is: is a dual stack host a v6 host (i.e. changes are
acceptable) or is it a v4 host (i.e. changes are not acceptable)?
Regardless of the current requirements, I would argue it is not acceptable
that dual-stack nodes need to be modified, for the exact same reason as it is
not acceptable that IPv4-only nodes need to be modified: deployment would be
highly impractical.
