Eric: knock yourself out. =)

Serhiy: What exception is raised in that situation is controlled by the eval loop, not importlib so that would be a separate change. But regardless, there is no way to infer whether you expected an attribute or module to be there, just that you were after something that didn't exist. But I would argue most people import at the module level and not the attribute level, and so raising an ModuleNotFoundError would be acceptable.
