My use of "application" is ambiguous. I was referring to the fact that DoH moves DNS from on top of udp/tcp to on top of https, itself on top of tcp, primarily to benefit from the 's' in https. I actually also run a DoH proxy on my home router and point dnsmasq (also on the router) at it, so all my home network DNS goes out over https.
