Allow me the chance to try and change you mind just a little bit.
The web is one of the most open platforms that has ever existed — period. Since the dawn of the smart phone the web developer has heard the following request: "I need a native app because push messages!". Execs want them, users want them. They literally bang down your door asking for the damn things. Allowing the browser to handle push messages means you can keep your app on this amazing open platform instead of share cropping in some app store.
