Presently, there is a lack of policy in this area, so ARIN has no direction to "pressure those who may be squatting on unused space simply because they signed up for it in 1990".  We do occasionally see attempts to hijack such space, and can revoke subsequent to a fraud report, and may soon have some recovery of blocks when they have no valid POCs, but at present the most likely path that completely unused space with active contact is going to come back into the system is via the specified transfer policy.  I know that may not be your own preference, but it at least results in overall improved IPv4 resource utilization.

Chris - There are numerous organizations that may appear to be defunct at first glance, but that does not make such a fact.  If we're notified by a contact from the original organization that they've shutdown, then we do reclaim the associated number resources.  Note that it's also quite possible that an organization has been acquired and no longer operates under the same name or location (but is still using the resources internally) or simply is choosing not to respond to ARIN's queries.

See "known defunct" above.

As long as we can understand the policy as defined, we will actively follow
any policy adopted.
