Why not set dispatch type as async ?

[adelin-b]

// index.d.ts
  /**
   * Dispatch an action to the background using messaging passing
   * @param data The action data to dispatch
   * 
   * Note: Although the return type is specified as the action, react-chrome-redux will
   * wrap the result in a responsePromise that will resolve/reject based on the
   * action response from the background page
   */
  dispatch<A>(data: A): A;

Why not doing
dispatch<A>(data: A): Promise<A>
