I didn't call it a sophisticated framework for nothing. Of course it does a lot more than that. Point is, it is ridiculous suffering from client side rendering latency penalties due to an absurd number of round trips loading all these different components. Concatenation is NOT a hard concept folks. Even if you aren't using GWT there is no excuse for letting this drive the problem.
