You are right. The largest ISP will reach the same end state regardless. I think the intent of the proposal, however was to prevent the larger ISP from consuming every available remaining IP, leaving nothing for the smaller orgs during the transition. The question is how to buy some time for the smaller orgs while the largest orgs work through the transition.

While I agree with what you're saying, I think that's also what will happen
_without_ any policy to cause it.

Large operators know their burn rate and how many customers they can add
before we all hit the wall, and they know they have to be planning for it
(and pressuring their vendors) now.  The rest of us don't really have the
power to do anything until a certain half-dozen ISPs that serve most of the
eyeballs in North America roll out v6, after which the equipment and
software will be available for everyone else to follow them.
