jpuffer opened a new issue #7871: Kubernetes Executor wastefully creates pods 
for DummyOperator tasks
   Kubernetes Executor currently spins up a whole worker pod to execute a dummy 
task.  We know Airflow's DummyOperator doesn't actually _do_ work - it's there 
to help to organize /group tasks and very useful for that purpose. 
   **Use case / motivation**
   For complex DAGs, skipping the worker creation process for dummy tasks could 
significantly improve execution time and resource use in the cluster.  Could 
the executor work more like the local executor when dealing with the dummy 
tasks? (that way, they could be essentially instant and not interfere with the 
actual worker pool)
