As I see it, there are four parts to this policy:
1) ARIN is required to perform the annual email ping.
2) Unresponsive POC email addresses shall be marked as such in the
database. As you note.
3) POCs which ARIN deems wholly unresponsive (likely after phone and
postal mail contact attempts fail) are marked as invalid.
4) Resources with zero valid POCs are cast out of the shadows for what they are.

There was a concern that removing the record could potentially cause
harm, where marking it appropriately was the best of both worlds; you
still have a POC to try, but you are aware that the POC is likely not
going to respond. For blocks with no valid contacts at all - perhaps
filtering becomes attractive, to mitigate your exposure.

Agreed, that policy is merely a first step and does not address reclamation.

To the extent that anyone believes there is a need to take the next
step and create a policy to push ARIN towards reclamation of unused
space, particularly space without a valid registrant, I have some
policy text put together and would love to hear from you off list. I
invite all interested parties to contact me.

Fair enough. I fully agree that address recovery is highly unlikely to
extend runout in any meaningful way. But I also agree with you that it
has value in other dimensions.

The problem that I see here is that in many cases it appears that only
folks on one side of the contract want the issues resolved, which
creates an impasse. How hard it is to overcome that impasse I am
unsure of.
