Review comment:
       I think the same problem exists here:
   
https://github.com/apache/beam/blob/89fc35b87d5dc074d25d60a97bb96d71e04be283/sdks/python/apache_beam/runners/worker/sdk_worker.py#L691
   
   Is there a way to see if the api service descriptor isn't the default 
instance instead of checking for the URL parameter?
