Since neither smith.name nor the wildcard *.name appear in the Public Suffix List (https://publicsuffix.org/), browsers would likely allow any page on a *.smith.name domain to set cookies for .smith.name.
There was an effort to properly handle the .name 2LDs, but it was never resolved because there’s no easy way to tell a reserved 2LD (open for 3LD registrations only) apart from a normal 2LD on .name: https://github.com/publicsuffix/list/issues/2306
So yes, this TLD’s setup is in fact pretty insane.
