Unfortunately there is no good solution. If you have a single
inheritance hierarchy and you do
not use super, you make it impossible for users of your hierarchy to
subclass it by using multiple inheritance in a cooperative way (this
is not polite).
OTOH, if you user super, your users must know about it, to avoid
unexpected cooperation. It is all explained in the "super harmful"
paper, which is a must read even if you only use single inheritance.
