At the moment, those are considered provisional data items so not included in the JSON files we use. If anyone has urgency, you could always go back and dig up the old XML parsing we originally did and pull from the XML files. I hope CLDR will soon include them in the JSON (maybe in v32 scheduled to be release mid November 2017). That would be a lot easier.
CLDR is adding subdivisions of its territory names e.g. http://www.unicode.org/cldr/charts/32/supplemental/territory_subdivisions.html. Those are pretty cool let's implement them in the plugin.
