[GitHub] [airflow] turbaszek commented on pull request #8296: Make execute and on_kill as abstractmethod in baseoperator

   From docs https://docs.python.org/3/library/abc.html :
   >Using this decorator requires that the class’s metaclass is ABCMeta or is derived from it. A class that has a metaclass derived from ABCMeta cannot be instantiated unless all of its abstract methods and properties are overridden.
   
   That's what I'm proposing in https://github.com/apache/airflow/pull/8805
