When I run the same thing:

  >import platform

So what is being proposed isn't very repeatable.

Difficult for developers to predict other environments.

One reason is the lack of clear documentation.

I'm only asking for clearer documentation.

Ok. That will work for future versions.

But it generates a nightmare scenario for application developers
installing on existing python installations. Their knowledge
must increase to be the same as your knowledge.

That is unfair.

But what is happening is that we are bypassing metadata by
including system calls.

That *ain't* metadata.

That is an error.
