There seems to be general consensus that diátaxis is a great theoretical model for structuring documentation.
However, using it – restructuring Python's docs – is a monumental task that needs some planning upfront.
@AA-Turner mentioned on the recent meeting that it would be good to start by charting the starting point: where on the Diátaxis chart do individual sections of the docs fall?
With that info we should be able to start planning where they should fall, and restructure/rewrite accordingly.
