I don't think it is quite as quick as that. You could not use NAMEPREP for
local-parts (some other variant of STRINGPREP would be needed, at the
least). And you would need to restrict the definition of local-part so as
to leave room for some way to detect automatically which ones needed to be
decoded and which ones really were that funny string.
The the main problem is that nobody is actively trying to generate such a
spec at the moment (and it is a job for the mail people, not for us).
