The devs don't really seem to have a clue about smartphone.

Lol, called it.
Incompetence and false bravado is all but guaranteed with development teams. Especially when it's closed source, not audited, and has minimal room for feedback loops.
You don't even need to audit a closed source app to know that Apple knows which devices its sending pushes to. It works because they know.
And how would they know that? That would mean push notifications would go via an Apple Server. Wich a) makes no sense b) can be masquerade so that the server does not know who talks to whom c) the meta information and the notification can be deleted timely
On the other hand, I guess most Android "low level" peer to peer apps go via FireBase?
All push notifications go through APNS on apple. That's Apple Push Notifications Service.
APNS requires the device to authenticate with it and can uniquely identify the device by an id. Its how it sends messages to devices.
Firebase cloud messaging acts the same way for true push notifications.
You don't need to audit a device using APNS or FCM on Android to know that it is not anonymous.
