  /**
   * By default, the po-formatter treats the pair `msgid` + `msgctx` as the source
   * for generating an ID by hashing its value.
   *
   * For messages with explicit IDs, the formatter adds a special comment `js-lingui-explicit-id` as a flag.
   * When this flag is present, the formatter will use the `msgid` as-is without any additional processing.
   *
   * Set this option to true if you exclusively use explicit-ids in your project.
