   Sounds interesting. It's pretty similar to pandas functions parameter - `errors={'ignore', 'raise', 'coerce'}`. But I see that there are a lot of different operators and sensors in Airflow that help you build complex pipelines with very simple blocks.
   
   I also implemented similar logic to RDS Operators with optional errors in the first iteration but after I decided to keep Operators as straightforward and simple as possible without any logic under the hood. 
   In this case, `GCSObjectExistenceSensor` might be useful. If something goes wrong you see it in the UI.
