A "Russian doll" problem 1

To revitalize a minority language, someone first has to pick one of the many existing varieties, develop it, codify it, write a grammar in it, make a dictionary in it, and teach it to promote it. People who speak other varieties of the same language feel disenfranchised. And they resist the top-down imposition of a "foreign" variety. Actually, the promoters of the minority language is doing exactly what they opposed and resisted when done by the promoter of the majority language.
