I, on the other hand, want to transfer more domains I've already done something serious with to CloudFlare Registrar, but can't because the TLDs (.club, .dev, .pw, and .sh in my case) aren't supported.
https://www.cloudflare.com/tld-policies/ says
Cloudflare is committed to supporting all available TLDs, with a focus on expanding country-code TLDs, and are working to expand this list. Check back soon for updates.
However, it has been saying this since the beginning, and comparing the current list to the October 2018 version (https://web.archive.org/web/20181025085340/https://www.cloud...), there are only 13 new TLDs:
bet Afilias
black Afilias
blue Afilias
green Afilias
io NIC.io
kim Afilias
lgbt Afilias
mobi Dotmobi (Afilias subsidiary)
pet Afilias
pink Afilias
pro Afilias
promo Get (Afilias subsidiary)
red Afilias
so really just one new TLD (.io) from a new registry, plus an Afilias (best known for .info) bundle. Still just a tiny number of registries, and almost no addition of ccTLDs despite the stated focus.
I wonder if you would be kind enough to shed some light on this situation?
