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

Prompted by 1.1.1.1 public DNS sending ECS ( anonymized )? : CloudFlare I ran some tests of my own and it seems all Cloudflare DNS addresses (1.1.1.1, 1.1.1.2, 1.1.1.3 and secondaries) are now sending anonymized IP addresses and ECS:

 dig +short @1.1.1.1 TXT whoami.ds.akahelp.net
"ip" "198.98.48.10" <== not my server IP and not modified by me, anonymized by Cloudflare
"ns" "172.70.229.13"
"ecs" "198.98.48.0/24/24"

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.

Cheers!
