I don't support this suggestion. I believe we need to move on from 
policies that require renumbering and then returning of blocks.  I don't 
think those really work after the free pool has been depleted, 
especially since ARIN isn't likely to actually reclaim the smaller 
blocks that we issued first.

My reasoning for splitting the /10 was to ensure that the 4.10.1 
austerity pool was large enough to serve the ARIN community.  Since the 
block sizes in the austerity pool are larger than the transition pool, 
the austerity pool needs to be larger to serve more organizations.

At the maximum allocation size, if this draft was to be implemented as 
currently constructed, this is the total number of organizations that 
could be served today.

8192 organizations (/24s) from a /11 under the transition pool 4.10.2

5120 organizations (/22s) from 2 /11s and 1 /12 under the austerity pool 

To me this seems like the right split.  This split could be adjusted in 
the future but at this time we are still setting aside more transition 
space for more organizations than austerity space.
