Web apps are improving in this respect. I'm particularly interested in stale-while-revalidate that has experimental Chromium support now: https://code.google.com/p/chromium/issues/detail?id=348877 https://code.google.com/p/chromium/issues/detail?id=348877 CDNs (at least Fastly) already support it, but browser support will give web app updates the option of working like native app updates.
