[arin-ppml] Against 2013-4

In the ARIN region, the "free pool" which supports "business as usual" can
go to zero.  What I mean by this is that with the exception of special use
space (say a /10 for transition mechanisms), all other space in the ARIN
free pool could go to zero, or fragments smaller than ARN can give out.

One might conclude that IPv4 allocations and assignments by ARIN is done,
and you can only get space on the transfer market.  This only remains true
so long as no organization returns space to IANA.  Lets
say hypothetically some organization feels they no longer have use for five
/8s, and don't feel their organization should profit from the sale of
addresses that were lent to them for a particular use that is no longer
needed (or maybe the organization doesn't want to profit from a transfer
because it is problematic to its charter).

In this case IANA would divide the space up five ways and give one /8 to
each of the five RIRs.  In ARIN's case this space would go in the "free
pool" and be available for business as usual, and fulfill any unmet pending

This is different from RIPE where this space would go into the soft landing
pool, and extend the amount of time new organizations could get a single
/22 (roughly double that window).

The point here is the free pool being empty is only a snapshot in time, so
I would challenge any argument that suggests we should remove needs based
allocation / assignments once ARIN's free pool depletes.

Certainly, considering a removal of justified need for transfers is a
different argument.  Lets try to keep those discussions separate.
