And here's where you wander off in the weeds...

How does reclamation in any way improve this beyond what is
accomplished by marking records with invalid/unverifiable POC
data as such and leaving them?

Seems to me doing an actual reclamation requires significantly
more diligence (effort/staff time/expense) on ARIN's part and
yields no additional benefit in this area.

The only reason to bother reclaiming is if you intend to reissue.
Since there does seem to be consensus that reissuing is of little
value, is there any reason to allocate resources to reclamation
instead of merely marking invalid/unresponsive records?

There are lots of possible ways to take care. There's no physical
pollution here and reclamation while it sounds all neat and tidy
really doesn't accomplish much compared to its costs.
