I have most of my domains on Google, but also have a couple on CloudFlare. I suppose I will just move them all to CloudFlare. They offer free WHOIS privacy and several other features for free. For those of you self hosting on a dynamic IP, there's a pretty good API that you can use for DNS updates.
I only have com/net/org domains, so I never noticed that. But you've provided good information. There is a list of CloudFlare supported TLD's here https://www.cloudflare.com/tld-policies/
