This sounds like it takes away a huge amount of creative freedom from the writers if the AI is specifying the framework. It'd be like letting the AI write the plot, but then having real writers fill in details along the way, which sounds like a good way to have the story go nowhere interesting.
I'm not a writer, but if I was to apply this strategy to programming, which I am familiar with, it'd be like letting the AI decide what all the features are, and then I'd have to go and build them. Considering more than half my job is stuff other than actually writing code, this seems overly reductive, and underestimates how much human experience matters in deciding a framework and direction.
