That all the cool 2-letter TLDs are designated as country codes was an extraordinary mistake that will have unpredictable and devastating consequences long into the future.
It's a commons-pollution problem. Are we going to have to start thinking of every word with a dot in the middle as a potential name? IMHO, a new gTLD is justifiable only when there's some concrete differentiator attached to it, e.g. .local indicating mDNS, or .it indicating "Italy"
What value is there in "horse.horse" being something you can resolve with DNS? What value does <something>.self give me, as a reader, that <something>.name or <something>.me or any of the other zillion variations on the same idea doesn't?
If anything, it creates confusion! "Oh, I met Bob McBobFace. Is he mcbobface.me? mcbobface.name? mcbobface.local?".
I have no objection to providing people with free subdomains under whatever assignment scheme you guys are using, but wouldn't <something>.net have worked too, and been a lot cheaper?
I guess I just don't get the value to the public of increasing the set of dotted word suffixes that indicate that a word is a a cognizable DNS object.
However .me (https://namegulf.com/tld/cctld/me) is a ccTLD managed by the Government of Montenegro, they set their own rules

I'd like to thank Caribbean island of Anguilla for having a ccTLD that helps identify which websites aren't worth your time in one quick look.
