This is more like an ApplicationLoader interface. The fact that the application
is loaded in another process is an implementation detail. The only difference is
the LaunchResult, which could probably be replaced by a  LoadResult?

+  LoadApplication(string url, mojo.Application& request)
+      => (LaunchResult result);
 };
