What would be the right way to differenciate between fallbacks like Picard -> French (there's a similarity between the languages, the message might even be the same) and French -> English (which is there just for having a base language). Take the fallback lists like shown in the message file, I guess? What's the prefered way to do that? Shouldn't we add in that case another parameter to Language::getFallbacksFor() to disable the addition of en as final fallback?
