so DNSSEC is the answer to, can I trust this IP is valid for the name news.ycombinator.com.
DNS over TLS/HTTPS just says, nobody but the DNS server I use can see I'm wanting news.ycombinator.com's IP. It's mostly useless at the moment, since other gaps exist leaking essentially the same information(SNI, etc), but it should get more useful over time, as people are working on fixing those gaps.
