Owen - It's not just "policies", it's "policies and strategies" in 2009-3:

"Each RIR through their respective chosen policies and strategies may 
 recover IPv4 address space which is under their administration and 
 designate any such space for return to the IANA"

To the extent that the intent of policy proposal 131 is to specifically
prevent returning space to IANA, it should state that very clearly, since
it is preempting existing adopted policy language.

Otherwise we end up with language in the PPML which specifically allows 
space to be returned to IANA (according to policies and strategies) and 
language elsewhere which states that space will be made available for 
registration and distribution in the ARIN region.
