Fragment of a discussion from Translating talk:MediaWiki/LiquidThreads
Because software developers usually want to be in control of their software: customising and changing the interface is quite different a task than translating it, it usually should not be equally easy. Besides, TWN and Translate don't support only MediaWiki and even MediaWiki development used not to be so tightly attached to TWN community.
