URL: https://github.com/apache/airflow/pull/6370#issuecomment-546647813
 
 
   I generally prefer this change but it should be worth noting where people are trying to get the last execution dates xcom value and are using `xcom_pull(key=key, include_prior_dates=True)` this will be a backwards compatibility break on retry.
   
   I don't know how heavily that is relied on but I don't know any other use of `include_prior_dates` so someone must of added it for a reason?
