All Cloudflare DNS resolvers now send ECS? (albeit anonymized)

Prompted by public DNS sending ECS ( anonymized )? : CloudFlare I ran some tests of my own and it seems all Cloudflare DNS addresses (,, and secondaries) are now sending anonymized IP addresses and ECS:

 dig +short @ TXT
"ip" "" <== not my server IP and not modified by me, anonymized by Cloudflare
"ns" ""
"ecs" ""

No worries, I only knew the link existed because I flagged a Cloudflare employee when it was first posted so they could explain the behavior.
