> Currently the logical operator DAG traversal is unnecessarily convoluted since it requires interacting with both MessageStreamImpls (which provides #getRegisteredOperatorSpecs) and OperatorSpecs (which provides #getNextStream). This would be cleaner if we separated these two graphs such that the framework tracks and interacts only with the OperatorSpecs graph, and the MessageStreamImpl graph is just a user-facing view of it.
