But in order to avoid this complicated mess about whether you can be compelled to provide your biometrics to unlock a device, the best course of action right now seems to be: Don't use them.
It seems clear that PIN/passwords are *not* treated the same as biometrics, and that requiring you to divulge a PIN number is different than demanding your fingerprint/facescan.
