Independent of IDN scheme it is important that the the solution is
considered as an upgrade of DNS, not a temporary hack, to have it
uniformly implemented.
If IDN is implemented as Nameprep+ACE I do not think that we will see
enough reason to replace ACE with UTF-8 on the wire in a foreseeable
future. Such a change would require that all DNS infrastructure is
upgraded. If UTF-8 is used, the ACE-to-UTF-8 and UTF-8-to-ACE conversions
can easily be handled in the interface to the DNS system.
Today we have three alternatives, as far as I can see:
1. UTF-8 without nameprep
2. UTF-8 with nameprep
3. ACE with nameprep
I do not consider "ACE now, UTF-8 later" an alternative.
