[arin-ppml] ARIN-prop-167 Removal of Renumbering Requirement for Small Multihomers

At the last ARIN meeting in Vancouver and prior to that in Philadelphia staff pointed out that almost no one was coming 
back to ARIN for additional small end user assignment. I believe the number quoted was 1 in Philadelphia and 5 in Vancouver 
of which many hundreds of people had taken advantage of getting /23 and /24 initial allocations. 

While I understand the concern with the routing table, this policy has erred too far to one side. 

There is also the issue of compatibility with 8.3 transfers. If an end user were to go to the market for a /24 would they have
to return the initial allocation and search for a /23 instead?
