Limit login to specific app

[gechoto]

Is your feature request related to a problem? Please describe.

I have a YT Music Premium subscription and want to use it in the official YT Music app. Unfortunately this app forces users to login and I have to due to the subscription anyway.

BUT YT Music is the very only service I really want to use from Google. The rest I want to avoid as much as possible and - at least have them not see my account.

The problem is currently when I sign in to YT Music I'm also automatically signed in to other Google apps.
I really do not like that Google Maps, knowing my location, is now linked to my Google Account as this is a huge let down for privacy.

So I immediately removed the account again. But now I can't use YT Music.

Describe the solution you'd like

Please add a per-app login or some kind of whitelist to only make the account available to specific apps and hide it from others.

Describe alternatives you've considered

idk

Additional context

There is a setting "Trust Google for app permissions" but it doesn't seem to fully work. For example I'm still automatically signed in to Maps and Photos. Just some account specific things are not working but they show the account as signed-in and see my account name / email. This is not good.

While being logged in to apps like youtube (or yt music), you can log out of other google apps (like maps).
Thats what I am doing atm. Chrome and maps are used without any account and youtube is used with my google account. Furthermore I am logged in to microG with my google account.

this would be a very nice feature but i would also add another feature like spoofing the Device type to prevent device based tracking and also maybe make it possible to use different Android ID's for a account or specific application if possible for a bit more added privacy.
