    The whole concept of IDN was fueled by the image of billions of Chinese,
    Indians, etc. who were forced to learn the Latin script in order to use
    the Internet, and who shouldn't have to.

    There was comparatively little urgency with regard to the speakers of
    German, Polish, Kobon, and Sencoten, who are already familiar with the
    Latin script but require letters that aren't available in non-IDN domain
    names. They had gotten along with Basic Latin approximations for years,
    and were largely expected to continue to do so. Domain names, after
    all, are not usually expected to be linguistically perfect.

    You missed my point entirely. There are 44 million speakers of Polish
    (Ethnologue). The balance between possible security problems and
    support for Polish-specific letters in domain names may be different
    from the balance involved in supporting letters specific to Kobon (6,000
    speakers) or Sencoten (3,000 speakers, to be generous).

    Not a bad idea.

    Vlad had written, "L WITH MIDDLE TILDE is used orthographically in
    Kobon." I assumed he meant U+026B LATIN SMALL LETTER L WITH MIDDLE
    TILDE.

    U+01C2 LATIN LETTER ALVEOLAR CLICK, on the other hand, doesn't look at
    all like an L with middle tilde.
