Like the others, I am not seeing the problem here. I set AF-C, 3D
tracking, Spot metering. Move the focus point to the side of the
frame. Put a bright object under the focus point, and a dark one
under the center point. Observe metering is correct.

So no matter which mode you're in, IT IS METERING ON THE (INITIALLY)
MANUALLY SELECTED FOCUS POINT. IT NEVER METERS ON THE CENTER POINT
(UNLESS YOU SELECTED IT)!

Now I agree it's annoying that the metering point doesn't track along
with 3D tracking, and I wish it did, but at least it's no worse than
the other dynamic AF modes (on D200 or D300), for which metering did
not track either.

What's the bug again?

In my test the metering does track in 3D 51pt AF-C.

I just setup my camera on a tripod set to AF-C, 51 pt 3d tracking, dynamic-area, and my wife moved an object from a dark wall to a window with good light. As the camera tracked the object across the screen from the wall to the window the meter did adjust in manual and in AV the shutter speed did change as the light changed on the object. On my D300 the exposure does change as it tracks.
I can't find the bug.
