msilib/__init__.py starts withfrom _msi import *: the _msi extension should be removed as well, no? Do you plan to remove it as a separated PR?

Note: The msilib module was used by thebdist_msi command of distutils, but this command was removed in Python 3.11, and the whole distutils package was removed in Python 3.12. See the bdist_msi deprecation in Python 3.9 for the rationale: issue#83767.

Now it's fine to remove this deprecated msilib module. Well,PEP 594 has a longer rationale.

Usingimport msilib|from msilib regex, I found the following projects of PyPI top 5,000 projects (at 2023-04-13) using the removed msilib module.

Affected projects (2):

• mpi4py (3.1.4)
• pygame (2.3.0)

pygame-2.3.0/setup.py: import msilibmpi4py-3.1.4/conf/mpidistutils.py: import msilib

DoesTools\msi\build.bat use msilib module or _msi extension? Or does it use Windows tooling instead?

There is.github/workflows/build_msi.yml which runsTools\msi\build.bat, but I don't know what triggers this GHA job. Is it when one file inTools/msi/ is modified?

It may be interesting to check that these tools and/or this GHA job still work ;-)

Oh wait, I see aTestsMSI / Windows Installer (x64) (pull_request) In progress task running! It will tell us if it still works :-)
