[address-policy-wg] aggregating unused allocations

For reference, in the ARIN region we just got rid of our aggregation policy
because it was almost never used, and staff had identified a loophole where
a large address holder could have requested a large aggregation block,
exhausted the free pool, and then taken their time about returning the
smaller blocks.

If you want to implement an aggregation policy in RIPE, it's probably worth
taking the ARIN experience into account and drafting the policy to deal
with those issues.
