   > @kaxil @ashb Should DAGs deleted via the UI actually be re-added if the file still exists? That seems to defeat the purpose of deleteng
   
   Couple of thoughts on this:
   1. Re-adding the DAG is useful; I consider it functionality equivalent to selecting all existing dag runs and deleting them. If I want the dag gone, I'll remove the underlying file first. Changing this would be a major departure.
   2. The fact the dag is not re-added is (slightly) missing the point. The problem is that the SLAs trigger a feedback loop that prevents the dag processor manager from iterating over all files in a finite time. This means that once this problem is present, _adding_ a new dag is also not picked up until / unless the SLA feedback clears down.
