   Indeed that's an interesting side-effect. We do not have DAG versioning 
implemented yet 
https://cwiki.apache.org/confluence/display/AIRFLOW/AIP-36+DAG+Versioning so 
those kind of problems are expected. As described in 
https://airflow.apache.org/docs/apache-airflow/stable/index.html
   
   >  Workflows are expected to be mostly static or slowly changing. You can 
think of the structure of the tasks in your workflow as slightly more dynamic 
than a database structure would be. Airflow workflows are expected to look 
similar from a run to the next, this allows for clarity around unit of work and 
continuity.
   
   We have currently no mechanisms to track version changes for DAGs, so if you 
do such structural changes, you might expect not only backfill to not work but 
also UI displays to be misleading. That's what DAG versioning (hopefully we 
will approve and start implementing on it soon) should address.
   
   Currently, the recommendation is to copy DAGs to another dag in case of 
structural changes like that.
