I think in this case it's not about signalling: in the linked discussion they are saying that the problem is the workload created by the AI-assisted creations, not the AI use in and of itself, and they are open to relaxing the restriction in future once they can figure out how to manage it.
reply(The issue is, I think, if you allow AI, no matter how many paragraphs you write about taking responsibility and ensuring high quality contributions, you're gonna get a lot of bad ones just because by sheer volume there's enough people who aren't gonna read it, and that's gonna take a disproportionate amount of effort to filter out).
Right, disallowing AI-generated drive-by PRs is completely reasonable; almost all of them should have just been bug reports or feature requests. If your AI was able to one-shot the code, the maintainers can do that themselves and it's going to be much easier for them to work with their own AIs rather than using you as a meat proxy.
reply> is myopic virtue signalling.
replyWould you personally join in to evaluate and review the onslaught of AI generated PR to the project?
