+ * ReadableStream, or a [BodyInit](https://fetch.spec.whatwg.org/#bodyinit),
+ * along with a
+ * [HeadersInit](https://fetch.spec.whatwg.org/#typedefdef-headersinit).
+ *
+ * Returns an object exposing a Response whose body consists of each individual
+ * stream's data returned in sequence, along with a Promise which signals when
+ * the stream is finished (useful for passing to a FetchEvent's waitUntil()).
+ *
+ * @param {Array<Promise<workbox-streams.StreamSource>>} sourcePromises
+ * @param {HeadersInit} [headersInit] If there's no `Content-Type` specified,
+ * `'text/html'` will be used by default.
+ * @return {Object<{done: Promise, response: Response}>}
