    Also, the "multiple scripts" wording does not specifically cover
    the all-Cyrillic case. So that part could be tightened up too.

The all cyrillic case is quite known by a lot of people. I seem to
remember court case about it dating back to even before IDNS was
discussed. Security sections are not necessarily describing all
corner cases.

    Also, O and 0 are mentioned, but is this technically correct?
    I mean, aren't uppercase ASCIIs supposed to be lowercased?

When the input to the encoding is consists of ASCII in the set LDH,
it wil be left untouched. For DNS is deosn't matter (case insensitive),
but the case should be preserved when possible. Only when the label
contains LDH, the ASCII is lower cased.
