We could simply always return a ResponseStream with helper support. It seems to be a no-op if an empty object is passed as the `metadata` argument.\r\n\r\nThoughts?","author":{"url":"https://github.com/astuyve","@type":"Person","name":"astuyve"},"datePublished":"2023-08-08T16:06:29.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":5},"url":"https://github.com/9/lambda-stream/issues/9"}
