Discovery: Automatically orphaning/deleting AUR packages

The requests queue is getting pretty filled with requests for packages that quite clearly have been abandoned with no chance of them ever becoming useful. It can be pretty exhausting to keep up with that queue!

In particular, there's a lot of "low-hanging fruit" packages that can be pruned from the AUR: Orphaned, 0 votes, last updated years ago packages are hardly worth keeping around.

Some prior art: 2014 enabled automatic acceptance of orphan requests after 180 days out-of-date. [1]

If automatically deleting packages on a schedule isn't welcome, would it make sense to at least explore a patch wherein a deletion request for e.g. an orphaned package/<10 votes/last updated >=2 years ago is automatically accepted?

That would alleviate a lot on both the dedicated requesters helping out as well as those working the queue.

This ticket is to iron out a complete spec for what we expect and can work towards: After that we can create tickets for work. This continues from a mailing list discussion.
