   Problem what to do about the person that need
   
   all_done_and_X_success where X could be 2 and not one
   
   Look like airflow is missing an expressive pattern to let the user implement any custom TriggerRule logic
   
   Maybe there could be an interface 
   
   ```python
   class TriggerRule(ABC):
   
       @abstractmethod
       def check_condition(self)->bool:
            pass
   ``` 
   
   that the users could extends and the current https://github.com/apache/airflow/blob/main/airflow/utils/trigger_rule.py would also implement that interface
