The Kafka Streams runner executes stages with `StateRequestHandler.unsupported()`, so a pipeline using side inputs cannot run. Supporting them means serving side input state to the SDK harness while a bundle is in flight, and holding the stage's watermark until each side input is ready. `BatchSideInputHandlerFactory` and `StateRequestHandlers.forSideInputHandlerFactory` are how the Flink runner does it.
