Administrative boundaries, such as municipalities, are included as parts of the language trees at the bottom.
I have several times suggested a "language" boundary type (with provision for minority languages etc.) and using the cleverness of subareas. The conclusion from the total lack of answers is that the OSM community is interested in neither (hence my astonishment reading this conversation). All the best, André. (*) be it only the possibility to show the boundaries as simply as in this message rather than saying look for and gather the boundaries with admin level=x or find and use a program that does it and if there is no admin level say goodbye to your project.
