In a sufficiently built system - like what Signal does, and like what most apps should be learning from - all the notification payload is getting is a "check for updates" command. You and literally everyone else are getting that generic notification all the time if you're in more than one chat. Just because Alice sent a message at 12:01PM and Bob received the generic "check me" notification at 12:02PM doesn't mean Bob necessarily received Alice's message specifically, because the notification has absolutely no concept of the messages period. Bob could have gotten that notification due to any of the other chats he's in. At best the argument here is that the government could use the push notification token to link a Signal account to a real username via Apple, but if you're that paranoid you shouldn't use an iOS device anyway. You also likely wouldn't use Signal due to the phone number issue.
