No, to add Unicode to domain names, and there are multiple reasons why it ended up like it did. LDH encoding is just one of them. The ability to have a different encoding in the future (different prefix than xn--, i.e. without destroying the full namespace) another.
But that discussion is something we do not have to have here.
Where I agree with you is that it does not matter whether we pass U-label or A-label as there is a 1:1 mapping between them, and that is as I have explained in other email messages not a big deal.
What people seems to ask for is the ability to pass a unicode string together with {A,U}-label so that the registry can say whether what is registered is really what the registrant asked for.
