Update
Permissions removed notification

Android 11 Developer Preview 3 has a new setting for app permissions, allowing them to be automatically revoked if you don't use the app for long enough. Disabled by default, the descriptively-named "Auto revoke permissions" setting will revoke permissions for a given app if it isn't used "for a few months."

The new setting is all the way down at the bottom of the App permissions section for each app (App info -> Permissions), and the permissions it can revoke seems to vary by app.
