Why is DOH only used for resolvers. What about authoritative servers. Caches are not authoritative soures of DNS data.<p>Nameservers for registries and registrars do not offer DOH. DNS over HTTPS is only used for "recursive DNS".<p>DNSCrypt has the same issue. It is used for resolvers only. It is possible to offer DNSCrypt from authoritative servers with dnscrypt-wrapper, but AFAIK no one does.
