Django causes latest setuptools to issue "UserWarning: Distutils was imported before Setuptools."

[Luc Saffre]

The latest change in setuptools 49.2 (released 2020-07-12, ​https://setuptools.readthedocs.io/en/latest/history.html) "now warns the user when setuptools is imported after distutils modules have been loaded (exempting PyPy for 3.6), directing the users of packages to import setuptools first."
That warning is a problem for me because it causes our doctests to fail. I might of course filter it out, but the proper solution would be to do what the warning asks. I don't import distutils myself. Is it possible that Django itself is misbehaving? Has anybody seen this warning as well?

Here is how to filter the warning:

import warnings
warnings.filterwarnings(
    "ignore", "Distutils was imported before Setuptools. This usage is discouraged and may exhibit undesirable behaviors or errors. Please use Setuptools' objects directly or at least import Setuptools first.",  UserWarning, "setuptools.distutils_patch")

But that code must run before importing django in every manage.py file, so it is not easy to disable in my test suite. Another workaround is to install "setuptools<49.2".

The problem does not occur in a virgin new django project, so the culprit might be some of the apps I use. I will report here if I find more relevant information.
