[arin-ppml] ARIN-prop-128: Replacement of Section

I oppose this proposal.

The current policy is clear and reasonably predictable. This policy makes
the date of implementation much harder to predict and also creates a situation
where the existing requests in queue when it happens will still receive
a 12 month supply, potentially taking the remaining pool beyond exhaustion.

I do not believe this proposal improves the current policy. Quite the opposite.
