And many more do every day. But it doesn't matter. What matters is if
people can type. Many people cannot type the full range of UNICODE
easily. But everyone writing HTML, C, Java, python can write

I don't speak only English, but I speak almost no Indonesian or
Afrikaans, still I can type it easily, since both only use the ISO
basic Latin alphabet AFAIK.

CLDR uses UN/LOCODEs which have the ISO 3166-1 alpha-2 country code as
the first two characters. But country codes can change, so this would
lead either to divergence of the codes as CLDR does, or to zone name
change caused by ISO 3166-1 alpha-2 changes

That folders are natural is something I have never heard before.
