That last phrase is the new part that proposal 2007-21 adds.

Can you point to where in the current policy one would likely
have to inflate host counts to be eligible for IPv6 PI space?

And by "easily", you mean renumbering current IPv4
resources in order to be eligible for IPv6 resources?

Why should historical IPv4 assignments hold up deployment of IPv6?

So you want people to renumber their historical IPv4 assignments
before being allowed to get IPv6 assignments?  Will this really
help v6 get deployed?
