The other part of the litmus test is "does the person submitting actually understand what they're submitting and why" - which is arguably not required for PRs that you'd otherwise accept, but since you have to put time and effort into determining whether a given contribution is ok to merge, it's common decency for the submitter to have done a self review first (AI or no AI)
Okay, who is going to wade through the noise to find the signal? You?
I mean, sure, I have to make the final determination. But you should not be sending me uncurated slop.
