The linked article is the PR talking about why growth has created a need to a written vision rather than an oral tradition.

I know this isn't in any way legally binding but I would prefer they added a statement on AI. Their policy is to tolerate "some AI assistance" but nothing more (https://www.gamedeveloper.com/business/godot-confirms-it-tol...), having that stance front and center would be preferable.
