The problem with that is that it is all or nothing. The milder approach I had in mind was that apps require you to register an account outside the app (like amazon) but the purchase is initiated inside the app and outside Apple api.

At the beginning that will be easy to simply not register and not use games that require registration. But well, micro-transaction started that way and nowadays all the major player do it that way.

Platform like XCloud that bundle various games from various studio will be used, and that basically mean you have a single app in your iPhone that can download a variety of content, all outside the control of Apple.

I'm not an idiot, I will whitelist and use the tool available in said platform, but that's one more thing to care about. One problem for which Apple just worked for me and won't anymore.

If i'm not mistaken, Apple doesn't even have a "separate wallet" requirement like Consoles do where, if you have a cross-platform game with virtual currency, you have to keep currency purchases made on one platform separate from currency purchases made on competitor's platform - Eg. in Fortnite, purchasing $10 of VBucks on the Nintendo Switch means you have to spend those VBucks in the in-game store while on the Switch, you can't go to your PC and spend them or combine them with VBucks you've purchased from Epic directly.
