Well, translation files are not versioned. Kasper designed it this way... So improving will mean redesigning translation system. I am only +1 to this because having the same translations for all versions is not good: lot of old strings around.

It cannot unless label exists in the default language. If there is no such label, what will translator translate? :)

I.e. if label exists for 4.1 but removed for 4.2, it will disappear from language packs and disappear in all languages in 4.1. Again, severe problem in translation system :(
