For the wider audience: though don't take this as GrapheneOS doesn't care about privacy. I'm sure there are reasons (I didn't read all of the linked threads) and it gives you plenty of other protections and tools - eg profiles, ability to disable all network access by app etc

It would have to be part of a larger, much more comprehensive feature preventing apps from finding other apps. That implies outright preventing communication with non-system components which is a much different approach to applications and rules out a lot of things. [...]

The open issue to restrict app visibility is [2].

With browser fingerprinting, the ad companies are already regularly pulling many shenanigans; I don't see a reason why this would be different.
