   * **This is an experimental API.**

   * **Please provide feedback!**
   *
   * This option helps the initial chunk loading of content scripts/the background service worker,
   * usually needed when `optimization.runtimeChunk` or `optimization.splitChunks.chunks` is used.
   *
   * This option accepts an object, where the keys are the entry name,
   * and the value is described below.
   *
   * This option replaces the HTMLWebpackPlugin where the background service worker and content scripts
   * do not use HTML to load files.
   *
   * If the value is a `string` (an output file name), for content scripts, it creates an extra
   * entry file to load all initial chunks **asynchronously** via dynamic import.
   * This asynchronous loading behavior is limited to the platform limit and **breaks**
   * [run_at](https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/manifest.json/content_scripts#run_at).
   *
   * If the value is a `string` (an output file name), for the background service worker (specified
   * via `options.background.serviceWorkerEntry`), it creates an extra entry file to load all
   * initial chunks **synchronously**.
   *
   * The file name specified MUST NOT be any existing file.
   *
   * If the value is a `function` (`(manifest: any, chunks: string[]) => void`), it requires
   * a "manifest.json" in the emitted files and lets you edit it on the fly to include all
   * the initial chunks. This option does not apply to the background service worker because
   * `manifest.json` does not accept multiple files.
   *
   * If the value is an `object` (`{ file: string; touch(manifest: any, file: string): void }`),
   * it generates a new file (see the behavior of `string` above) and provides a callback to
   * edit the `manifest.json` (see the behavior of `function` above).
   *
   * If the value is `false`, it asserts that this entry does not have more than one initial file,
   * otherwise, it will be a compile error.
   *
   * If the value is `undefined`, it silences the warning for the background service worker.
   *
   * You can also change your configuration to avoid `optimization.runtimeChunk` or `optimization.splitChunks.chunks`,
   * in this case, webpack only generates 1 initial file so you don't need this option.
   *
   * @defaultValue undefined
   * @example
   * ```ts
   * {
   *     // creates a entryName.js that dynamic import all the files needed.
   *     "contentScript1": "cs1.js",
   *     // edit the manifest.json directly to load all files synchronously.
   *     "contentScript2": (manifest, files) => {
   *         manifest.content_scripts[0].js = files;
   *         manifest.content_scripts[1].js = files;
   *     },
   *     "backgroundWorker": {
   *         file: "backgroundWorker.js",
   *         touch(manifest, file) {
   *             manifest.background.service_worker = file;
   *         }
   *     },
   * }
   * ```
