But why would anyone, want to register that half-Latin, half-Cyrillic
mess of a broken label, when the all-Cyrillic label would make more
sense to register, unless they had a dubious motive for doing so? And,
if the registrars actually played by the _existing_ IANA rules, none of
them would let it be registered in any case.
I would like to believe that in a properly-run IDN world, registering a
label like that would be the equivalent of registering an incorrectly
normalized Punycoded label. Yes, in some sense it might be technically
possible to not care about normalization forms, but in practice they are
there for a good reason, even though they represent a reduction in the
overall space of possible labels. Similarly, I think that the IANA/IETF
community are going to have to enforce some more restrictions on labels
if the IDN universe to make IDN safer to deploy, to prevent it from
being Balkanized into a locked-down old-ASCII world and a world of
second-class spoofable IDN domains.
