I think I can answer this by saying I don't believe anyone has submitted such a request to the devs to make something like this happen. A lot of things might be "built" without actually being in-game. Usually posting things in general forums is not enough and can often be overlooked by those who need to know about them.
That post was dated 7/30/2007, and on that date Chongo and I were in the last stages of updates and testing. I can say that if we had an area to put in at that time, it would have been included. If we had to build one, it's questionable whether or not it would have made it in. I'm pretty sure neither of us was informed directly about this addition, though given the chaos, stress and overloaded schedules at the time, it could have been missed.
This is not a matter of excluding anything but rather of what was communicated to us in time to make a difference. Perhaps someone is building the area right now for inclusion, but if it is, I'm not aware of it. If someone gets an area, or at least a detailed description to Chongo, I'm confident he can work it in to an upcoming update.
