The posted example happens to work because object has
a default __init__ method that does nothing. But this
is not generally true of other methods, which means you
need a "terminating" class at the end of the MRO whose
methods don't call super.
Speaking of new-style classes only, don't they all end in object? And
if the MRO is only known at run-time, how is one to know at code-time
whether your (new-style) class is at the end of the line?
