Their queue IDs are user IDs. They use a different one for each contact in 1:1 chats, but that doesn’t make them anything less than user IDs; you can do the same thing on any other chat service by creating a different account for each contact.
Do I understand it correctly that the queue ID is specific to the group chat? How is that a user ID, then? The point is that the user doesn’t have an ID, and so you can’t find them in any other group chats unless they have introduced themselves. It basically only identifies the destination, and you really can’t avoid that, can you? Well, unless all messages are basically broadcasts, and everyone receives them, generating unimaginably larger traffic

And in group chats, they don’t even do that.
