nit: Rephrase the comment to match the request->create renaming.

Does this method now create a new route, or potentially re-connect an existing
one?

Done. It only creates a new route. We will have a separate function for join.

   // |callback| is invoked with a response indicating success or failure.
-  virtual void RequestRoute(const MediaSourceId& source,
-                            const MediaSinkId& sink_id,
-                            const MediaRouteResponseCallback& callback) = 0;
+  virtual void CreateRoute(const MediaSourceId& source,
+                           const MediaSinkId& sink_id,
+                           const MediaRouteResponseCallback& callback) = 0;
 
   // Closes the media route specified by |route_id|.
   virtual void CloseRoute(const MediaRouteId& route_id) = 0;
