Can __queryParams become public?

[ergo]

Hello,

I'm dispatching some events in form of:

this.fire('redirect-url', {
    path: '/admin/app-resources/edit/' + response.uuid + '/' + response.resource_type
});

Now I'm receiving them in my top level document:

    handleRedirectUrl: function (event){
        console.log('handleRedirectUrl', event);
        if (event.detail.path){
            this.set('route.path', event.detail.path);
        }
        if (event.detail.params){
            this.set('route.__queryParams', event.detail.params);
        }
    }

However double underscores don't give confidence if this API should be accessed by me at all. Can we get some confirmation if it will be safe for us to use?

@ergo A safe way to change path is to do the following

     switchPath: function(path, params) {
        window.history.pushState({}, null, this.generateUri(path,params));
        window.dispatchEvent(new CustomEvent('location-changed'));
      },

This is push the new url and then dispatch the location-changed event. <iron-location> and then in turn <app-location> see that and respond - setting up the route for <app-route>. I have this function in a behaviour which gets included in many elements. It doesn't need any centralised management (<iron-location> is in effect doing that)

Note the generatURI function just encodes the params object as query parameters and appends it to path

Maybe this? https://github.com/PolymerElements/app-route/issues/154

Isn't it supposed to be used with app-location in the form of:

  <app-location route="{{route}}" query-params="{{queryParams}}"></app-location>
  <app-route route="{{route}}" pattern="[[rootPattern]]:page" data="{{routeData}}"></app-route>
