I am not a major contributor or anything but I have a hobby of watching issues and pull requests for "coding drama". These AI policies seems to be targeting the average AI PR, which is basically one or two shot implementations. In some projects which are more AI positive (like AI agent projects) I have seen people's code reviews are also AI. It just looks like one AI config checking the output for other AI configs. In my own contributions I have at least had a couple of instances where I didn't know I was talking to an LLM or a person.

Of course as people understand how to use these tools their quality of output may increase. But what will also improve is our own processes around handling AI work.
