RE: " So basically you'd remove the whole feature just cause one package no
one installs abuses it. Doesn't make sense."

No, the point being made is *at least* one package that was found on PyPI
is abusing it, so it exists and we need to consider the possibility others
are also abusing the feature.

For the ones you know about. Dealing with abuse of functionality isn't
about what common practice is, but what a bad actor may do.

Trust me, from my perspective of the Python extension for VS Code you
cannot ignore system installs.
