iPhone gyroscopes, of all things, can uniquely ID handsets on anything earlier than iOS 12.2

Please don't do that

"[T]he actual technique does not necessarily have to be malicious in practice (for example, a bank might use it to uniquely fingerprint your phone as an anti-fraud measure)"

About that... NO! The bank does not need to fingerprint my phone, given that they won't be fingerprinting anyone's non-Apple devices. Nobody needs a unique fingerprint that I can't wipe. History to determine whether a request is likely to be legitimate or not, sure. Sneaky tracking data, no. In addition to it being creepy, it wouldn't actually help very much given that only a small number of devices can use it even if Apple unpatches the vulnerability.

Saying things like that makes it sound like you think there is a legitimate use for this invasive technique. There isn't.
