While I agree with you, I think it is already possible to make a "browser" on iOS today that tries to steal your data. The only thing stopping it is manual review, not any technological measures. In fact, if the point of an app is to steal your browsing data, it is easier for them to stick with WebKit and WKWebView than to invest in a new browsing engine. Existing APIs provide plenty of opportunity to inject almost annything into web views.
