I've put them in here for now to track the currently available configurations in the existing KinesisConsumer and ensure we have parity. If desired, I can remove them, but I would prefer to keep them for now, and do a cleanup before we release (given that this is marked as @Experimental) -- This is an automated message from the Apache Git Service.
