Re: execution_date - can we stop the confusion?


I dont think this makes sense and I dont that think anyone had a real issue with this. Execution date has been clearly documented  and is part of the core principles of airflow. Renaming will create more confusion.  

Please note that I do think that as an anonymous user you cannot speak for any "new airflow user". That is a contradiction to me. 

Thanks
