One thing to reclaim space that has been "high jacked",  another thing to reclaim it from organizations who do have some reasonable non-arbitrary basis for believing they have a legitimate claim to such space....such as a Bankruptcy Court approving said transfer or a contract from the entity which is legitimately listed as holder of that space in the registry.

In such a case, it is unlikely that they would be unable to complete a section 8 transfer with ARIN.

Absent completion of such a transfer, IMHO, it is indistinguishable from hijacking. It is an organization with no policy basis for having the addresses using addresses that were registered to a separate organization. That's pretty much the definition of hijacking.

Fortunately that seems to be what has happened in the well publicized transfers so far.

Agreed. I think ARIN and current policy have done a good job of that. There are no documented cases that I am aware of where this has failed so far.

When it comes to legacy addresses, there is much uncertainty until there is a contract with the RIR.

Reclamation of blocks in questionable status and no longer under control of the registrant is, frankly, one way to reduce the uncertainty.
