I think this is unreasonable. The lower-case forms ("НР" vs "hp")
look quite differently, and browsers typically display domain
names in all-lower in the address bar.

The other question, of course, is whether two-letter domain names
should be allowed in the first place, but this is off-topic. If they
are allowed, you should not ban pairs of cyrillic or greek letters
just because they are homograph with a latin combination. Then,
the same would apply to Greek vs. Cyrillic.
