One of the funny things about Bible translations is that more modern translations are based on older manuscripts than older translations, due to advances in archeology. SE can't carry any translations that incorporate the insights of the Dead Sea Scrolls, and having access to some of the oldest Hebrew manuscripts is a pretty big deal when it comes to translating the Tanakh.

It's true, modern versions of War and Peace can't be hosted at SE, but those modern versions generally don't reflect revolutionary leaps in archeology :)
