[notnullorvoid]

You are missing the point of the original argument.

It's not that the project maintainer can use a LLM to generate a PR, it's that they choose not to.

To relate it closer to your argument. As a someone involved in a project that does X, I would find little value in collaborating with the "author" of another project built with AI to do X. Where as a project doing X were the authors actually wrote, understand the code, and thus the problem space better would be extremely valuable peers.
