Did you read the replies of the maintainers? They were rational, level-headed and graceful. They also recognized that in the future their policies are likely to evolve as LLMs are likely to be able to autonomously contribute with more signal than noise.

If that wasn't an upfront rule, it's disrespectful to the work done by the AI. "Take this PR, then change the rules for future ones" I'd understand. Also, I doubt my objection will be affected: are they now banning pros from contributing to good first issues?
