This seems like a very nicely done implementation. One negative: I don't think people realize how easy it will be to inadvertently include server side files in client side bundles. The technical approach mitigates this and is well designed. But simply by blurring the lines it might result in sever side config bundled to the client. (Easy to mitigate, just add a line to server side stuff which and destructs if it detects wrong environment)
