Currently there is a fixed list of supported languages in the settings.
We plan to move to a setup where we support multiple languages per country e.g.
The German hardware page should be translated in: German, Turkish and English.
The Dutch hardware page should be translated in: Dutch and English
This is necessary since the content varies based on the country due to regulations.
By allowing us to extend the supported languages we could avoid workarounds like using other locales or splitting the page into multiple pages.
