The closest thing you can do is talk gTLD and ccTLD into putting some
record at _xyz.TLD that tells root level of deligation for that TLD.
Unfortunetly cases like .US make it worth since there are multiple

You haven't done it. I have - large database that is hard to maintain.
Here is one for well-known domain for example (which does both 2nd
and 3rd level deligation):
DoWhois_MainDomains(Buffer, Query, "whois.cira.ca", "", 6, "SUBDOMAIN:",
"on.ca, qc.ca, nl.ca, pe.ca, nt.ca, nu.ca, bc.ca, ab.ca, nb.ca, ns.ca,
yk.ca, sk.ca, mb.ca", querylevel);
Here is another less well-known:
DoWhois_MainDomains(Buffer, Query, "whois.nic.hu", "", 13, "DOMAIN:",
"co.hu, 2000.hu, erotika.hu, jogasz.hu, sex.hu, video.hu, info.hu, agrar.hu,
film.hu, konyvelo.hu, shop.hu, org.hu, bolt.hu, forum.hu, lakas.hu, suli.hu,
priv.hu, casino.hu, games.hu, media.hu, szex.hu, sport.hu, city.hu, hotel.hu,
news.hu, tozsde.hu, tm.hu, erotica.hu, ingatlan.hu, reklam.hu, utazas.hu",
It goes like this for almost every large-enough TLD (for others I often
simply don't know).
