ICANN requires that a gTLD adopts the following policy before freeing it
from a general contractual prohibition on accepting IDN registration:

"All code points in a single label will be taken from the same script as
determined by the Unicode Standard Annex #24: Script Names
<http://www.unicode.org/reports/tr24>. Exceptions to this guideline are
permissible for languages with established orthographies and conventions
that require the commingled use of multiple scripts. Even in the case of
this exception, visually confusable characters from different scripts
will not be allowed to co-exist in a single set of permissible code
points unless a corresponding policy and character table is clearly
defined."

Of course, if there were any language that is so regularly written with
mixed Cyrillic and Latin letters that a justifiable TLD label could be
proposed with them, root policies might require additional constraint.
Asking again -- is there any such everyday writing system? If not,
putting this on our agenda is redundant at the very least.
