Disclosure. If LLMs are used in service of open-source projects, then they are relevant, but clearly many in the community feel that to be negative, and therefore there should be a disclosure. Someone can make open source software using closed-source tooling already, so disallowing one form of tooling entirely is letting a moral reaction interfere with how we understand open source.
Linux would have to be removed from discussion, for example, if all LLM-contributed projects were to be disallowed. I don't see why rules should be made with explicit exceptions in mind, yet excluding Linux cuts out a huge portion of open source discussion.
