   When doing operators for adding labels it would be good to check if they work with lineage operators (`>` and `<` afaik).
   
   @andrewgodwin would you mind elaborating more about the use case for the labels? In my understanding all the actions are performed by tasks and edges in DAGs represent only order (and sometimes data) relation. Adding a label would suggest that some action is performed between tasks. Is it done by XCom or something?
