SceneService exposes popAllSubScenes method?

[chengenzhao]

Hi:

Is it a good idea allow sceneService provide popAllSubScenes method?
in the source code mainWindow object does provide this method
but currently sceneService doesn't expose this method
so is it a good idea to provide this method in the scene services?

Currently we are using while statement to pop all sub scenes

    /**
     * Pop all subscenes.
     */
    open fun popAllSubScenes(){
        while(currentScene.isSubState)
            popSubScene()
    }

it works but is it better to expose it in the sceneService directly?

        override fun popAllSubScenes() {
            mainWindow.popAllSubScenes()
        }

thanks
