Taiwan is not a "legacy" country, but I think the point is that the article's claim, that the ISO 3166 country codes correspond to UN seat holders, is false.
I apologize for any bad wording. Didn't intend to say that Guadeloupe was a legacy country or anything, nor Taïwan. The legacy part was about using something other than UN recognition (before using that rule). You're right about the point I wanted to make.
