Zero-tolerance no-AI policies are tiresome. I get why people have concerns. No PR reviewer wants to review drek the submitter him/herself doesn't understand. And LLMs have been a disproportionate source for such drek. But the actual problem they're trying to solve should be low-quality submissions, rather than spending energy fulfilling some notion of AI-free purity.

The linked issue raised the complaint that a bit of text as a "wall of text" (implication, I guess, too many words, too little meaning). Maybe it was or wasn't. But being generated by an LLM doesn't make it a wall of text, and being written by a human doesn't make it not a wall (speaking as somebody who has been fairly accused at times of generating 100% human-made walls of text).
