I believe Safari will improve though. Currently Apple has little incentive to put more money into Safari because there’s no competition. Once they have to open up iOS to competition, they’ll spent more money on Safari to stay competitive. The web is still an important platform they cannot just ignore. And they have the resources and the know how, so they have a good chance of succeeding. And they will still be the native and default choice (even with browser choice), so they will also have that advantage still.
