Hello John,

I think this should happen sooner or later. However, Anne van Kesteren 
recently pointed out that the major browsers haven't yet done too much 
with respect to implementing UTR 46, which I'd guess implies that they 
haven't yet implemented much of IDNA 2008, either (Anne, can you confirm 
or clarify?). Given that browsers are an important part of IDNA users, 
it might be prudent to wait for some more time and see what issues might 
come up from that side.

(That was also why I asked Marcos about deployment of "ß"; the story was 
that registries would first deploy these with the respective bundlings 
or restrictions, and then browsers could move ahead and resolve them 
directly.)

Regards,   Martin.
