Good! There's at least a viable alternative to ISO3166 country codes to
differentiate languages

For example, ca-s-CI (using the "-s-" <extlang> mechanism) will be a much better
alternative to ca-es-CI (with ISO 3166-1&2). And we'll be able to differentiate
the 3 other variants of Catalan in continental Spain (two of them are in
cross-border regions in Andorra and France), or the 4 main dialects of Breton
(whose which don't cover the administrative division of Britanny into French
departments), for example "br-s-van" for the Vannetais variant of Breton spoken
and written around the city of Vannes.

Another good example will be the case of Flemish (also cross-border between
France and Belgium).

One very useful case will be something like "zh-s-traditional" and
"zh-s-simplified" (is there already proposed extlang tags for them?) which will
be much better than the choice between "zh" for simplified Chinese and "zh-TW"
for Traditional Chinese (to be used even by users in Hong Kong, Macau, Singapore
and even South China that may prefer the traditional form).
