Maybe a side issue but... Why must specify each operator in it's own import? Why can't we just something like do from airflow import operators,hook
and all operators & hooks will become available. We don't have that many and even looking forward to the future it's unlikely that it will grow by hundreds. Almost any package that I work with it's one import and that is it. Airflow is very unique in the landscape sometimes I have 13 rows of imports :\ Having 1 import as mentioned above will prevent also cases of breaks when files are moved from one path to another in the project.
