I'm fine with Klingon and I think we're getting to the point slowly. :)
For me it's not only the language packs. It's all the "logistics" in the background to manage post and meta translations for user generated content. As WordPress does not cover this, there are plugins making it easier to manage translations. (Maybe I shoud've used "translations" in the first place.)
And I understand it is a lot of time and effort to make any system capable of handling multiple languages simultaneously. But everyone starting with WordPress needs to evaluate the possiblities there are of translating content (which is well described in the codex) and most likely sticks to one method to increase productivity for future times.
Knowing that WordPress was actually a blogging system (and usually one only blogs in one language) I understand it wasn't top priority at the beginning. But as WordPress longs for greater things, why not including such an important thing soon? Is it just to keep WordPress as lean as possible or is it on the map but there are other things with higher priority? Or...?
