It is possible to define an extended DNS protocol that supports
non-ASCII domain names directly. This can be done at any time, or
never. There was no need to hold up IDNA while the details of non-ASCII
DNS were worked out. Similarly, there is no need to hold up IMAA while
the details of non-ASCII message headers are worked out.
IDNA do not support all international domain names due to being madenon-ASCII domain names directly. This can be done at any time, or

to work using unaware DNS servers and clients.
As the IMAA draft stands today it will not handle all e-mail addresses.
It would be better if we first defined how things like URIs, domain names
and e-mail addresses look like using UCS in the international context.
When that is done, we can look at possible downgrading to ASCII to support
legacy systems.
By starting with encoding into ASCII it is easy to miss ways people expect
a name to be used.
