That is why it is not recommended to mix Latin and Cyrillic. A label 
should contain only either Latin *OR* Cyrillic, and not both. If 
registries wish to support both scripts within a label, it SHOULD 
implement bundling in order to minimize the risk of homographic attacks.

The "i" you mentioned in "Львів" is "U+0456 CYRILLIC SMALL LETTER 
BYELORUSSIAN-UKRAINIAN I" so the whole label is in Cyrillic. It is in a 
single script and therefore there is no need to forbid them.

So, I'm not sure I understand your view. Maybe I missed something.
