Sorry, confused. Https requests are prolific, while encrypted DNS requests aren't. Why isn't the former less hard to detect?

How would you tell that an encrypted chunk of data is HTTPS instead of DNS? The best you'd be able to do is guess based on behavior that it's DNS.

Destination port might be easy to differentiate dns over tls vs dns over https :)

Perhaps if the attacker filters traffic first by protocol, it's harder but not at all impossible. I'd guess that DNS-over-HTTPS packets won't be hard to identify by other means.

of course dns over https to cloudflare can be mixed on the same h2 connection with other https to the same host. It starts to get interesting.
(this is one of the advantages of https vs straight tls)
