Usually in the hierachical  DNS system, the resolution delay of domain names like EXAMPLE.ONION is less than that of those like EXAMPLE.ONION.EFF.ORG. So maybe we should consider more about does the TLD (like .ONION) is really needed?

Well, that's what local caches and long TTLs are for. But in this case, any query of this kind that hits the real DNS is by definition junk (it's a query for a name from a non-DNS namespace that has leaked into the DNS) so I can't imagine what performance difference this could possibly make.
