Yep, and they worked with the person in the open source community who initially started doing this:

Things like this help reassure me that OS X will remain a viable option for a while. Sure, the top layer may change to be more user friendly, but they will keep toggles around somewhere for the more advanced users who need to get under the hood. The 10.8, and commitment to yearly releases helps me to believe they will keep OS X and iOS separate, but share ideas where it makes sense.
