Hang back on this one for the moment, there is an update coming due to some small changes in the api repo.

Per the comment, note that this type is slightly a lie: the real API Response type for streaming has a oneof message as the only field. But that oneof currently contains only one possible result: a BatchAck, which is itself empty. All of this is in furtherance of not breaking compatibility for old clients if and when additional response data types are added, which is anticipated. For now, it seems reasonable to keep the type silent, since the existence of a reply on the stream is implicitly a batch ack (it can't be anything else on the wire).

OK this is good to go now.
