Default constructor and extends null

At the face to face meeting we agreed that if no constructor is
present in a class a default one is provided as if the following
constructor was present.

class C extends null {
  constructor(...args) {

What should this do when C extends null? If this was manually added I
would prefer that this would be a runtime error. Should we special
case this and use an empty constructor if the super class is null?
