Relies on DNSSEC or CA to validate keys (pp. 22). Not a good idea of your threat model is governments. Defines fairly arbitrary list of non-extensible metadata

Relies on DNSSEC or CA to validate keys (pp. 22). Not a good idea of your threat model is governments. Defines fairly arbitrary list of non-extensible metadata including gender, alma mater & political party (pp. 60). Seems like this should be extensible and predefining a lot of that is short-sighted.
