As Steven noted, the normative answer to this is in PEP 8: https://www.python.org/dev/peps/pep-0008/#public-and-internal-interfaces Since `os.errno` is a transitive import, is not included in `os.__all__`, and isn't documented in the library reference, it's considered an implementation detail that can be removed without a deprecation period. That said, it should still be mentioned in the "Porting to Python 3.7" section of the What's New guide, with the fix being to switch to "import errno" in any affected code.
