Thank you very much!

Knot DNS already have similar infrastructure in the place to support dynamic responses (the dynamic modules - IP(v4,v6) PTR/AAAA/A synthetis is a fine example what we can do), but more modules are missing. Any hint on what we should focus first? We will probably introduce online signing first before adding more modules, but, hey, if you can to discuss your needs on the mailing list we would be happy to hear about other deployment needs.
In Knot DNS: A high-performance, authoritative DNS serverThe authors of this are CZ.NIC (whose website is confusingly http://nic.cz). They're the same people behind the thoroughly awesome Turris Router (https://www.turris.cz/en/). The complete hardware design for this device is open and I can vouch for it being a very awesome bit of kit.
The benchmarks for the DNS server are very impressive. Way beyond our needs though: we're doing a few hundred million queries per month, so ~100qps. Knot handles >500k qps! We've recently switched our authoritative DNS from djbdns to gdnsd (https://github.com/blblack/gdnsd), primarily due to the GSLB features.
Lots of great stuff coming out of CZ.NIC - if you're reading this, keep it up!
In Knot DNS: A high-performance, authoritative DNS serverFair enough. https://github.com/blblack/gdnsd <- I take it.
The reason Route53 excited me is it has failover, healthchecks, etc. built in in a way I can sleep through things failing without anything breaking.
I don't actually use 2 million DNS queries / month, yet. But if I implemented DNS-based failover and shortened the TTL from the 12 hours I have now to something like 5 minutes? Ya, that'd clear 2 million pretty quickly. ;)
