   * `default`: A factory function to set the default value of the data, before the async function resolves - particularly useful with the `lazy: true` option.
   * `pick`: Only pick specified keys in this array from the `handler` function result.
   * `watch`: watch reactive sources to auto-refresh.
-  * `initialCache`: When set to `false`, will skip payload cache for initial fetch (defaults to `true`).
   * `transform`: A function that can be used to alter `handler` function result after resolving.
   * `immediate`: When set to `false`, will prevent the request from firing immediately. (defaults to `true`)
