See #3046

This will probably need some type hints to be added for read_csv, either as a contribution by us or a third-party.

Would be nice to have a bug that tracks resolution of this specific case, it has come up multiple times #4001, #4428 and was not resolved by #3046

@qubitron When pandas-dev/pandas#14468 is resolved then we'll get the benefits. Alternatively, we can race them to implement the stubs ourselves...
