See:

• https://peps.python.org/pep-0632/#migration-advice
• Making setuptools the reference implementation of the distutils API pypa/packaging-problems#127
• Deprecate SETUPTOOLS_USE_DISTUTILS=stdlib pypa/setuptools#3625
• Deprecate usage of import distutils except internal to Setuptools pypa/setuptools#3622
• Deprecate distutils_hack and support for 'import distutils' before 'import setuptools' pypa/setuptools#4137
• https://docs.python.org/3.11/distutils/

  The entire distutils package has been deprecated and will be removed in Python 3.12

• https://docs.python.org/3.12/distutils/ (empty page, now lives at https://setuptools.pypa.io/en/latest/deprecated/distutils/ )

Since pywin32 already imports setuptools, the module will still be found with Python 3.12, but falls in the "deprecated" category.

Exe installers support will need to be dropped to completely stop using distutils directly. See #1939
