Not that I know of, except a change I made earlier today in speech. Unfortunately the PB definitions are bundled with grpc, so it's tough to parse the Any fields in the operations returned from the API (gRPC or JSON-over-HTTP) without importing the PB types.

@dhermes Gotcha. In that case I'm fine with this outside of datastore, logging, pubsub, storage, and logging.
