Title: A parameter should be able to use as the value of a factory-method.

All definitions except the factory-method are resolved by $this->getParameterBag()->resolveValue() method in the createService() method, but the factory-method is not resolved by the same way. Thus a parameter cannot be used as a factory-method definition.
