This is suboptimal because it limits the opportunity for nameservers to measure RTTs and contact the fastest server.
So it adds a very small amount of work (and maintained state) for the DNS resolvers. Not a big deal.
TLD operators should make up their mind: either control their servers, or trust the people that they gave control to to make these kinds of decisions.
Currently, with the present ICANN procedures, this is not an option. ICANN knows only the TLD managers, not the nameserver managers. For ICANN, rip.psg.com depends on the TLD it serves, not on Randy Bush. (It would be a sensible model, but a different model, with different actors.)
