It's even more complicated than that.

Since PEP 8 asks you to sort your import into blocks of standard library, 3rd party packages, and app packages, a non-trivial insight into the packaging situation of the current app/package is required. Thus it makes sense to punt on it, since it would open a completely new can of worms and the code is already present in isort.

Right. But Black's documentation also says that it is not supposed to change the AST at all, except in a small number of special cases which should not affect runtime behavior.[1] Since import-reordering actually could change the runtime behavior, I think they consider it permanently out-of-scope, rather than just "too hard."

(As mentioned before, there is no good reason for import-reordering to change runtime behavior. It's just that Python doesn't have any hard limits which prevent you from shooting yourself in the foot like that.)
