I would also ditch the 80% requirement; in fact, I'd suggest avoiding
any hard-and-fast number, as it's likely to be completely orthogonal
to the intent of the proposal.

Note that at least one company that I'm aware of is making their content
available via IPv6 by making use of v4-to-v6 proxy boxes; thus, the number
of dual-stacked ports is a tiny fraction of the overall network, but
it nonetheless
provides IPv6 reachability to the rest of the internet6 for that
content.  Surely
that would suffice to meet the underlying desire of the proposal, that
we provide
encouragement for further deployment of IPv6?
