On my notebooks, I run two Docker instances of AdGuards dnsproxy, using my own DNSCrypt resolvers as upstream servers. This setup provides anonymity from the resolver and protects against man-in-the-middle attacks, since DNSCrypt authenticates DNS responses. However, root DNS queries from the upstream remain unencrypted. Additionally, not all nameservers support DNSSEC, so a fallback is often needed. Which can still leave the upstream vulnerable to man-in-the-middle attacks. Of course, DNSCrypt is more secure (authentication, no bootstrapping), faster and anonym (against the resolver). But i think it is still not useable for "normal" people. And as a provider, the setup is more complex then DoH, DoT or DoQ, because of cert rotation and the DNS entries.
