I hereby declare myself pleasantly amazed with GDOT. Sometime since my last visit to 285-400, crews removed the no-longer-needed sign for the Peachtree Dunwoody Road exit... AND scooted the battleaxe mega-BGS over by a lane so that it correctly indicates lane five rather than lane four as EXIT ONLY for Roswell Road. They also removed one of the arrows from the EXIT ONLY panel for 400, which I'm not sure is an improvement- - it's lane five, not lane six, that leads to 400 south. There must've been quite a bit of discussion about it.
My reflex is to say that it would've been nice if this had been done promptly, but maybe it was. I don't frequent this part of town-- I was there today for a doctor's appointment. After all, it wouldn't have been possible to scoot that BGS over until the Peachtree Dunwoody sign was removed. So, I offer a cautious tentative attaboy to GDOT and the 285-400 project team.
As stated in the post I quoted below, the earlier configuration would almost certainly have been correct once the dreaded reduction of the mainline to three lanes happens, which I thought was supposed to be in June. I suspected that GDOT had decided to erect and live with incorrect and misleading lane assignment signage until then. Maybe the big switch has been delayed, or maybe the operational effects of the erroneous signage had become intolerable enough to compel them to mitigate them. We'll never know, of course. Presumably, when the big switch happens, they'll move the sign back to its previous location.

On Saturday I drove 285-400 for the first time since the new westbound 285 to southbound 400 ramp had been opened. Here's the revised mainline signage, taken from the Perimeter Center Parkway bridge. As you can see, the signage indicates that three of the six lanes are dropped at the exits for 400 and Roswell Road. My intention when heading west on 285 was to exit at Roswell Road and double back east on 285, so I moved from lane five into lane four as the signage indicates. After the 400 exit, I saw that there was still a lane to my right which was headed to Roswell Road, and the lane I was in stayed on the 285 mainline. Thanks, GDOT. I realized what was going on in time, but how many others won't?
The sign will be correct when the 285 mainline is narrowed to three lanes, which is now supposedly planned for June. We'll see, I guess.
