I end up feeling the same way, for purely pragmatic reasons. However,
cooperative multiple inheritance is a respected religion, and when
practiced systematically can work well.

Also make a big distinction between super calls of __init__ (which are
a Pythonic wart and don't exist in other languages practicing multiple
inheritance AFAIK) and super calls of regular methods (which are
virtually problem-free as long as you agree on a base class that
defines a method and derive from that class when you want to extend
it).
