I suppose it's intended to be used by people who are used to the US layout, but who want to be able to put a few types of accents onto a few vowels. There's upside down punctuation, no C cedille, no enyay. I don't think so anyway. It may be that ~N produces an enyay, in which case it would be just as annoying to use in the Unix world as one of the other national layouts.

I think basing your actions off an assumption like that is a slippery slope that is going to get you in trouble.
