On a tangent: the origin of the problems with low-quality drive-by requests is github's social nature. That might have been great when GitHub started, but nowadays many use it as portfolio padding and/or social proof.

"This person contributed to a lot of projects" heuristic for "they're a good and passionate developer" means people will increasingly game this using low-quality submissions. This has been happening for years already.

Of course, AI just added kerosene to the fire, but re-read the policy and omit AI and it still makes sense!

A long term fix for this is to remove the incentive. Paradoxically, AI might help here because this can so trivially be gamed that it's obvious it's not longer any kind of signal.
