That's one way to provide a very high level view. But there is actually
a certain ammount of scariness already in the case of (letter only,
single direction) labels of both directions being used in one and the
same domain name. And then indeed things get more and more scary,
but there may be steps back to less scary stuff, and context is
also highly relevant.

I would personally be extremely okay with what you propose above
(letter only), but not everybody may have this opinion, so I wanted
to give a somewhat more detailled picture of the situation.

Regards,    Martin.
