Fragment of a discussion from Translating talk:MediaWiki
The point is not harassing translators continuously by telling them that a message is untranslated (both in Special:Translate and in statistics) when the message doesn't require translation. Your link shows 160 titles different from "Wikipedia", but for instance that includes 12 occurences of "Википедия" which only needs to be translated once in Russian for all the others to pick it up.
