Disclaimer: I used to work for a browser company but I no longer do. I never 
spoke for them anyway.

For me, one of the key elements and features with DoH is that I as a user have 
picked a DNS provider I decide to trust. Be it a global CDN provider or my own 
cloud instance. Any other way, with the ISP or my local network admins telling 
me what server to use, is a major setback in my view.

All forms of opportunistic DoH will make it no better than opportunistic DoT, 
which ultimately will fail to protect my privacy.

At the same time I of course appreciate that there's a problem/challenge here 
with figuring out what DoH server to use and how to even find out that there 
is one offered. If I don't know any servers, getting one or a few suggestions 
might help. For this, this spec offers ways and I'm for the working group 
adopting this.
