DEP 0008 ('Formatting Code with Black') was accepted by the Django board last week. They're going to wait until Black has a stable release before reformatting all the code, as there's at least one thing they don't like about how Black handles things.
Seems like there are two things they want to see fixed:
> Several developers report that, in their experience, Black made code formatting worse and decreased readability. Concrete examples shown in the discussion were short lists, which Black reformats when they fit on a single line, and vertically aligned comments, which Black is unable to preserve. This is being addressed [0] in Black and is expected to be resolved before Black becomes stable.
