I read somewhere that Chrome will be adding DoH (DNS over HTTPS) and I'm not sure if it's some experimental flag you toggle. I imagine they will be using 8.8.8.8 (which supports DoH). So now you are sending all your personal data to Google instead of Cloudflare :o But you can always use another DoH provider if you dislike Google or Cloudflare[0]
I imagine any browser worth its salt will eventually switch over to DoH as the default as time goes on, as it's a great feature even though it doesn't honor the /hosts file or honor pi-hole[1] configured routers, it's still a great feature to have.
