the rules we use are 6 years old! we still need to use the public
suffix list to figure out the zone name by default for ease of use.
Domains like co.uk will only appear in the suffix list and not in the
tld list (https://www.iana.org/domains/root/db)
To verify if the list is updated:
node -e "console.log(require('tldjs').getDomain('whatever.framer.ai'))"
The above will output "whatever.framer.ai"
