That would seem to be an interesting modification to the proposal--adjust the
language so that *new* allocations from ARIN should be matched by a
corresponding IPv6 deployment, but that v4 transfers are not likewise

Given that transfers are likely to cost real $$s, that provides the more gentle
encouragement for companies; if you want it for cheap from ARIN, pony up
with some v6; otherwise, pay market rates for recycled space.

Depending on the wording, I might be able to support a modified proposal
along those lines.
