I wonder how they plan to detect it something is LLM generated. I think what this leads to is people just working hard to make their outputs appear human generated.

People could also rip code verbatim from BigCorp's confidential source and try to hide it. It doesn't mean they should have a policy that allows that.

And that's fine - if LLM generated code is indistinguishable from human-written code, AND there's a person behind it or in the maintainers that fully understands it, then there is no issue.

But I don't think generated code in itself was ever the issue. It's who takes responsibility for it. And I think in this case, can the submitter guarantee it's not code that is copyrighted elsewhere.

Long time contributors risk expulsion. First time contributors will face additional scrutiny. Slaving over your LLM extrusions to make it appear human made, thereby reading and reviewing it, is an acceptable outcome.
