It is positive that many of these legacy holder returned some of their unneeded IPv4 resources in the past. However I personally believe it is something negative that there is still a fair amount of these addresses unused and not even announced to the DFZ as if they were waiting for some big Internet event to happen.

I really don't mind Legacy Holders to keep addresses that were assigned to them ages ago as long they have a justification for using them. In the other hand I am unable to believe any organization in the entire world that is not a Telecommunications or a Hosting Company is able to technically justify more and a single /8.

If this community wants more resources, the more obvious place to find them isn't some relatively small block held by an organization or individual that might be deceased, this community could try and convince the DoD to release some portion of their very large /8 assignments.  That could be fertile ground.  Who knows how many IPv4 addresses they are actually using and need.

I've never heard of it happening but it wouldn't surprise me if ARIN has quietly discussed this possibility with the DoD as some point.
We wouldn't hear about it unless resources were actually released.

Already happened (more than a decade ago): the US DoD, BBN, Stanford, Interop, etc. all returned some of their unneeded IPv4 resources after being approached by ARIN – the address space was returned, held for a period, and then issued by the policies in place at that time.
