Something like that, yes. For packages that publish wheels, we can
analyse those directly without needing to run setup.py. Of course there
are many packages with only sdists published.

Potentially. As I mentioned, there is a place in the metadata to put
this information - the 'Provides' field.  However, relying on package
uploaders would take a long time to build up decent coverage of the
available packages, so I'm inclined to focus on scanning PyPI, similar
to the tool Chris already showed.
