That tooling argument is quite weak. PDM is the only tool I was able to find that has support for __pypackages__, the paths it uses seem to be slightly different to the PEP wording, and it uses a $PYTHONPATH/shell hack (`pdm --pep582` adds a folder with `sitecustomize.py` that does the magic). How do you change the $PYTHONPATH used by an IDE (and its magic features)?
