All of this can be reason to reject an app during submission review. Google and Apple could update their guidelines and start enforcing them.
I mean if I would Apple I would go even stricter. In Info.plist you declare list of domains which can be accessed with webview and reason why. Just like you declare reason why you should have access to photos or a camera. Everything other would straight open in browser.
Also there is a solution to make component which acts as a webview, but in fact is blackboxed main browser which app has no access to, just like PHPicker photos select in ios 15
