Well, you don't really need to announce anything, if the AI-generated submissions were super helpful anyways.

But yeah, I guess, all I can say is that I really don't believe your theory. Especially Widelands could've done so many other things in the past, if they cared so much for attention.

But I have also been in the maintainer role, having to deal with generated submissions, and it really isn't fun. I'm talking specifically about fun, because these are community-driven projects, so you need volunteers to have fun for anything to happen.
In theory, a generated code submission could bring useful changes to the project, but it still isn't fun to review, because there isn't a human on the other side that you can teach. Even worse, you're effectively just talking to an LLM through a middleman. If I wanted to use an LLM, I'd use it directly.
