when looking at the sitematrix.json in the parsoid repo (mediawiki/services/parsoid), the variable "localname" seems to be inconsistent.
For most languages it is set to the name of the language in English, but for some it is set to the name of the language in the language itself. compare, for example:
"localname": "Chinese" "localname": "Classical Chinese" "localname": "Chinese (Min Nan)"
vs.
"localname": "беларуская (тарашкевіца)" "localname": "भोजपुरी"
Besides making this consistent, it should probably be clarified what this "localname" really means here. Do we just assume English as the local language for sitematrix and that is a problem in itself?
