That’s just systemd adding a birthdate field to their userdb. Doesn’t require that it be filled out or accurate, and especially doesn’t require it to be validated against a government database. I don’t see it as fundamentally any different from adding a userdb field for favorite color, phone number, or blood type.
Without 3rd party validation, I really don’t see the privacy issue with an age field. Without verification, it is, at worst, one more byte available to hash into a unique identifier, but you can feed that field from /dev/random at every query and poison even that hypothetical.



Making the government small enough to fit into every aspect of your life. No crevice too small.
