I would agree that this is the goal we're trying to optimize for.

I agree that with a 60 month justified need threshold we do have a risk of
organizations will acquire more space than they have immediate need for,
and that the addresses will not be in use for some time after they're
transferred.  However, there is another case we need to be sure not to
ignore.  If organizations holding (and not using) legacy space are
disinclined to transfer it due to ARIN's restrictions, then those addresses
will not be in use (or held by those that have justified need) either.

I'm not sure that 60 months is the right threshold at this time, but I do
think we need to figure out how to balance the incentive for address
holders to release space to those with justified need against the
possibility that organizations will acquire more addresses than they have
immediate need for.
