I'm not sure we should be too worried about that. Inheritance in Python has always been more about implementation than interface, so Liskov doesn't really apply in the same way it does in statically typed languages. In other words, just because A inherits from B in Python isn't meant to imply that an A is a drop-in replacement for a B.
