I don't like the way Cloudflare is centralizing everything, but I would use Cloudflare any day over my ISP. Seriously, fuck my ISP.
I would support this feature on the condition that users are able to choose which DNS service to use by default, especially as more public DNS services begin to adopt DoH. Developers like us will also need the ability to use /etc/hosts or route queries to a local instance of dnsmasq.
Obviously there's a switch somewhere in about:config, because Firefox is also involved with the Tor project which requires the ability to route DNS queries through Tor. This switch should be accessible to the user, just like the choice of default search provider.
