Not sure about Android, but Apple has gone down the path of limiting functionality for web-apps versus "Apps".
Web app functionality has always been limited on all platforms. Access to things like cameras, GPS, etc is restricted. In our case we are writing what will most likely be fairly boring business apps, not funky games or sales websites. So, I think access to phone resources like cameras, etc is probably not so important. Of course, iOS lover will push this aspect so we should have some arguments against it - like it being fucking pointless for our apps. :)
