It doesn't feel great but it doesn't feel awful. In Australia (admittedly a place that people already label as authoritarian) you need to provide DL or passport to activate a SIM, and those are already linked to biometrics so this doesn't feel like too much of a reach. But I guess some hellish future exists where telcos start selling/capitalising biometric info, so yeah...
