I think the idea is not necessarily to make fully offline websites (though some people will), but to provide a more consistent interface akin to native apps. Most apps you use require network access but you can still interact with them on very slow/broken connection. Meanwhile you try to load a website and it’s a much different experience. But as for offline apps, I could imagine music/podcast players (where you can save offline media), offline maps, etc.
