Honestly, my view is that this is a technical solution for a cultural problem. Particularly in the last ~10 years, open source has really been pushed into a "corporate dress rehearsal" culture. All communication is expected to be highly professional. Talk to everyone who opens an issue or PR with the respect you would a coworker. Say nothing that might offend anyone anywhere, keep it PG-13. Even Linus had to pull back on his famously virtiolic responses to shitty code in PRs.
Being open and inclusive is great, but bad actors have really exploited this. The proper response to an obviously AI-generated slop PR should be "fuck off", closing the PR, and banning them from the repo. But maintainers are uncomfortable with doing this directly since it violates the corporate dress rehearsal kayfabe, so vouch is a roundabout way of accomplishing this.

This is maturation, open source being professional is a good sign for the future
I disagree. The problem with AI slop is not so much that it's from AI, but that it's pretty much always completely unreadable and unmaintainable code. So just tell the contributor that their work is not up to standard, and if they persist they will get banned from contributing further. It's their job to refactor the contribution so that it's as easy as possible to review, and if AI is not up to the task this will obviously require human effort.
What on earth makes you think that denouncing a bot PR with stronger language would deter it? The bot does not and cannot care.
If that worked, then there would be an epidemic of phone scammers or email phishers having epiphanies and changing careers when their victims reply with (well deserved) angry screeds.
