Comment (by dcf):

 Perhaps you saw already: Cloudflare's DNS HTTPS server sends an `Alt-Svc`
 that points to an onion.
 https://blog.cloudflare.com/welcome-hidden-resolver/

 > We don’t think you should need to remember this address. Ideally, all
 you would need to do is go to [https://tor.cloudflare-dns.com/ https://tor
 .cloudflare-dns.com] and have the browser route your request to the .onion
 address. This is possible using the "[https://tools.ietf.org/html/rfc7838
 Alt-Svc]" HTTP header which is an optional header notifying the browser
 that the resources can be accessed from an alternative network location,
 possibly using a different protocol. Thanks to
 [https://hacks.mozilla.org/2018/05/a-cartoon-intro-to-dns-over-https/
 Mozilla], using .onion addresses as alternative services is now possible
 in [https://nightly.mozilla.org/ Firefox Nightly].

 When I go to https://tor.cloudflare-dns.com/, I see
 {{{
 Alt-Svc:
 h2="dns4torpnlfs2ifuz2s2yf3fc7rdmsbhm6rw75euj35pac6ap25zgqad.onion:443";
 ma=315360000; persist=1
 }}}

 As far as I can tell, the `Alt-Svc` header doesn't actually ''do''
 anything yet in Tor Browser (maybe it does in Firefox), but there is
 #26365.
