It doesn't impact IDNs, but, when we start to look at IRIs and
other pieces of syntax, the use of hyphen as a canonical
separation marker in XML-based media types, language names, and
other things that are expected to be parsed internally do bring
it fairly close to being a syntactic protocol element.
To the extent to which any of this discussion impacts
stringprep, the interactions between stringprep and non-IDN
protocols implies that we need to tread _very_ carefully.
