All right, but this is okay:
class C(B, A): pass

With the semantics I was suggesting if C calls super, but A doesn't
then B would still get called.
which is contradicted by:
"Siblings", in the context of a single MRO are thus classes between
which there is no sub-class/super-class relation.
So I maintain that the situation is far from clear. :-)
