> nonstandard TLD
What exactly is non-standard about an ICANN-approved TLD? Yes, the multi-level structure is a little odd, but given that ICANN approved it in the first place, one has a reasonable expectation that they would work as advertised.
Non-standard as in "it's not up to my usual standards" not "is not part of a technical standard". I.e. it's a gTLD rather than a "standard" (in the previous sense) TLD.

Uh, 99% of people would assume a .name address is a scam. Hate to break it to you.
I have a .science domain and a .com domain.
Even though .science was launched in 2014 (more than a decade ago), I still consider it a non-standard TLD and still deal regularly with difficulties around its use. (For instance, you wouldn't believe how many online services reject email addresses than end in .science because they use regexes that exclude TLDs with 7 letters.)
Likewise, I've registered .lol and .fun domains but never would have assumed that just because they're available now, they will be available in perpetuity.
In that sense, .name as a third-level TLD is even more non-standard, because the standard way domain registration works is by choosing a single "second level" domain name, then adding subdomains.
