Any idea where I can see a timeline for this change? I’m eager to see a decent browser on ios.

It will only change if the developer goes ahead and makes a special EU version for the app. And many wont, because that takes too many human resources to do and maintain. This was a rule made by Apple on purpose, together with all their other malicious compliance moves: they made it hard for developers so devs will just keep everything as it always was and not use the new EU exclusive things

It could change based on EU regulations, I seem to recall Mozilla saying they weren’t going to maintain two versions though.
