It's not the tools, it's the quality. No FOSS dev would care where the code came from if it followed the contributor's guidelines and coding style.

This is why it's a spam issue. a bunch of low quality submissions only gum up the time of such developers and slows the entire process down.

>that likely means extremely competent maintainers and contributors.

Your assumption falls apart here, sadly. Dunning-Kruger hits hard here for new contributors powered by LLMs and the maintainers suffer the brunt of the hit.
