How can I get into the large area in the bottom-right of the Sundari Flatlands?

Start off here — (1495, 1359) near the Upper Sundari Outpost:

After jumping up the rocks you'll get to this grassy plateau:

At the back of which is a path:

Head down here:

Hang a right:

You've made it! This place is entirely empty, panorama:

But there are some invisible walls/floors:

This is overlooking where you head up:

It's hard (though not impossible) to get back out the way you came, but there's plenty of other ways out like just jumping down in the image above. I was hoping for a datacron or something here (why else would I spend so much time trying to get up there :P), but nope. Maybe something is planned for here in a future update.
