Why is Cloudflare missing from your DNS list on WIFI routers ?

When examining the list of DNS providers on your WIFI router Cloudflare which is considered popular is not on your list. I know a DNS can be manually added but I would like to know why you do not include Cloudflare? From the latest version 3.0.0.4.386_53370
