Sure, I don't really have any right now. In the long run I think that will be impossible. When my TV dies I have to make a lot of compromises to get a dumb display with(out) all the other neat features.

Also, moving DNS to the application instead of the OS just makes managing my well behaved applications harder. It used to be possible to set this automatically through DHCP, now I have to audit every application and make sure it is using my preferred DNS and also manually configure those applications.

DNS-over-HTTPS in Firefox doesn't really benefit me. DNS-over-HTTPS with a DHCP configured server in my OS would be a beneficial option.

Really I would prefer something like DNS over TLS because that solves everything. DNS keeps working, intermediate parties can't read my DNS requests and I can reason about my network traffic, at least on devices I trust.
