Actually I'm more worried about things like scrolling.
Dropping offline storage is such a big deal there would be a major outcry (plus it would destroy their marketing claims that Safari is the best browser - regardless of whether that is true or not).
But if the mobile safari user-experience is just a little bit worse than a native UI then that would cause real problems - especially on an Apple platform where there are large numbers of developers who notice and find that kind of thing important.
Yeah the difference in inertia on Safari's scrolling has been bothering me for a while so I feel you on that. There are a ton of places where I think native apps are better than a modern web app right now but I think that's just the state of the web. The browsers are all improving rapidly but the bar set by native apps is rising as well.
