It seems that the frustration with super revolves around how Python currently conflates (as well as many users) two very different types of inheritance, both "is-a" and "has-a" (or compositional) inheritance. Unfortunately, Python assists this confusion because the language doesn't provide a distinct enough way to differentiate between them.
has-a should be modelling with attributes, not inheritance. The latter relationship should always mean is-a (even for mixins).
Cheers, Nick.
