 Review comment:
   That makes sense and I'm actually running into this issue while updating 
SDKs. We probably have to add environment_id to WindowingStrategy since it's 
not directly attached to PTransform.

> Currently Environment is not a top level attribute of the PTransform (of 
> runner API proto).
> [https://github.com/apache/beam/blob/master/model/pipeline/src/main/proto/beam_runner_api.proto#L99]
> Instead it is hidden inside various payload objects. For example, for ParDo, 
> environment will be inside SdkFunctionSpec of ParDoPayload.

> This makes tracking environment of different types of PTransforms harder and 
> we have to fork code (on the type of PTransform) to extract the Environment 
> where the PTransform should be executed. It will probably be simpler to just 
> make Environment a top level attribute of PTransform.
