Because of mainly two reasons:
1. Backward compatibility with ascii domain names where domain names are in use in protocols.
2. The problematic part of IDNA is not the encoding, but the choice what characters to allow etc. If we one day need a completely different version of IDNA, then we can use a different prefix than "xn--" and still we have not destroyed the complete Unicode name space.
