The language reference [1] says:

  Ultimately, the loader is what makes use of __file__ and/or __cached__

This implies that loaders should use __file__ and __cached__ when loading a module.  Instead loaders are meant to implement exec_module() and use the spec that's passed in.

The entire section should have a clear note that loaders are not meant to rely a module's import-related attributes.
