Having been the most vocal on this matter I think I can tell:
- as long as IDNA was supposed to the be the only way to support
indigenous names this was a problem. The responses given by James and
Vint about ML-DNS remove that concern.
- the argumentation introduced by Debbie's ISO/TC46 failed NWIP last
year raised interests in some security areas (police, passports,
banks) that could be better addressed through the security oriented
universal code that RFC 5242 tries to joke about.
- I would however suggest to use ISO 10646 rather than Unicode for
serveral reasons :
- political in several countries and cultures
- to clearly define the technical perimeter being involved
- proponents/searchers/projects towards a security oriented code
belong to the ISO, JTC1 and Open Norms & Standards IGF spheres rather
than to IETF/Unicode spheres.
- for consistency with further developments in connex semiotic
areas. They will probably be more extended ISO and ONSIGF than at Unicode.
This also permits to welcome the inputs of the numerous Unicode
members and of their employees as contributions rather than negociations.
"IDNA uses the Unicode character repertoire, for continuity with
IDNA2003" clearly shows that the use of Unicode or alternatives was
not to be considered by the WG, speeds up its conclusion and will
clarify the implementation debate.
