[docs] [issue30026] Hashable doesn't check for __eq__

> # Can't instantiate abstract class X with abstract methods

Sorry, this is how ABCs are supposed to work.  They use @abstractmethod to specify requirements that a subclass if required to implement.  The ABC metaclass then enforces that requirement, preventing instantiation unless those requirements are met.  If not met, they give a reasonably clear error message, "TypeError: Can't instantiate abstract class A with abstract methods __hash__".
