Original GitHub issue: https://github.com/hickory-dns/hickory-dns/issues/1939

I couldn't find an RFC for this, but RFC9250 (DoQ) mentions:

DNS over HTTPS (DoH) [RFC8484] can be used with HTTP/3 to get some of the benefits of QUIC.

This would probably use the h3 crate.

Is the reasoning on this one based on the port usage? I think this should be possible. I haven't reviewed the h3 crate, so I don't know how hard/easy it would be to enable this.

I assume so. My impression until now was that the only advantage DoH has over DoT is that it hides behind HTTP traffic. So I assume DoH3 vs DoQ is the same.
