We used to check some environment variables here about suppressing packaging warnings - looks like import os got left after those were removed in #5619. Pylint won't moan about unused imports in __init__ by default I think, because most names in an initialiser won't be used.

upgrade:
- |
In this version, ``from qiskit import *`` will not import submodules, but only a selected list of objects.
This might break existing code using ``from qiskit import *`` and referring to objects that are not part of the current namespace.
As a reminder, ``import *`` is considered bad practice and it should not be used in production code.
Qiskit sets ``__all__`` in ``qiskit/__init__.py`` as a way to mitigate the effects of said bad practice.
If your code raises ``name '<something>' is not defined``, add ``from qiskit import <something>`` and try again.
