Hi, I am not sure if you got the point which I criticize. While with some effort we could create an interface on Wikidata supporting several badges [1] we are still facing a problem on the client. How should we choose the badges that should be visible on Wikipedia against those that aren't relevant in the "in other languages" section? I know, one answer is to add another config variable, but this is only a short solution because it will end up in adding another config and even one more so that we finally will have content in the code base. This is something we should really avoid.
Also there exist some mockups already on Commons [1] [2].
