It seems like there might be some justification for restricting Nitro from UIWebView because then you have to trust a third party app... but a webapp launched from the home screen is completely controlled by Apple's apps just like if you launched it from Safari (except less annoying). Surely these home page webapps can be treated just like Safari?

Not quite. In essence, a native app using UIWebView is created on the fly, and past that point it acts just like a standalone app. Only real-deal Safari gets the exception.
