Not if the user chooses a different default browser.

I doubt all the Chromium clones would evenly support "normal" iOS integrations, and the ability to (privately) deal with, for example, universal links, App Clips, or even that banner offering a website visitor to use the native app.

I understand the sentiment for wanting to use custom features on desktop, but a phone needs to be much more reliable than this - you can't have something working "sometimes" or for users to have to retry or change settings on the go. Imagine a stressful situation at the airport, and the app you are using needs you to switch browsers or download another app to work...
