Aren't there many examples of these? For example IMEI, IMSI, phone number, etc?
Even without "unique" signals, isn't it fairly trivial to identify a user with a handful of "not very unique" signals? User-agent, a few recent IP addresses, browser capabilities, list of installed apps, device operating system properties, etc?
