but their stated reasoning is that they do open PRs to train up new contributors and eventually get them into the community where they'll be more trusted. That doesn't suggest a hardline stance against the tools to me necessarily at least.

On one hand, you could be right! I am making inferences on low data, judging the Godot team based on some of their _strong_ design choices. I would have a better argument if I spent the time tracking the Github issues that seemed quite wild that we encountered while building in Godot. Top of mind (low evidence, sorry) GDScript as a base scripting language (later reversed by C#), refusal to add async/await for GDScript, others that have escaped me.

What I am saying is squishy conjecture.

On the other hand, they're training new contributors to make internal AI-assisted PRs by requiring them to make non-assisted PRs? That sounds unlikely but I suppose possible.
