This isn't so bad as .com.mx and .mx should be on the public suffix list then.

But letting arbitrary customers take arbitrary 3 level domains, and others take 2 level domains, seems like a mistake as it's not very reasonable for every 3LD customer to put the 2LD on the public suffix list, but mixing 3LD and 2LD registrations means you can't public suffix *.name.

Seems the whole idea of having both was always misguided.

uk is one example - they opened up x.uk later, and gave x.co.uk registrations first dibs.
