Many open source contributions are unsolicited, which makes a clear contribution policy and code of conduct all the more important.

And given that, I think "must not use LLM assistance" will age significantly worse than an actually useful description of desirable and undesirable behavior (which might very reasonably include things like "must not make your bot's slop our core contributor's problem").

There is a common agreement in the open source community that unsolicited contributions from humans are expected and desireable if made in good faith. Letting your agent loose on github is neither good faith nor LLM assisted programming, it's just an experiment with other people's code which we have also seen (and banned) before the age of LLMs.

I think some things are just obviously wrong and don't need to be written down. I also think having common rules for bots and people is not a good idea, because, point one, bots are not people and we shouldn't pretend they are
