Shameless plug - Knot DNS Resolver has out-of-order replies, query deduplication + pipelining, and TCP fastopen.

There's a PR open for DNS/TLS started at the OARC hackathon, but it wasn't finished. It would be terrific if somebody could pick that up, so we could have some real-world useable implementations for testing.

Out-of-order replies, for instance.
