It certainly looks pretty bad, but I really never noticed. I noticed the hacking, kicking, and bucking of the Multi below 3.5k rpm (Disclaimer: the one I tested
was super bad, there seems to have been improvements and the 2013 adds a lot of improvements for this, too) much more and it annoyed me much more than the weird torque curve of the boxer.
I had a 2010 R1200GS and this curve was barely noticeable when riding. There was a bit of a dip around 5k rpm, but it wasn't bad or so. And in normal riding, the behavior below 5k was much more important for me. I'm not certain how much you'll actually feel the dips on the new one. Time will tell.
I did some Photoshop ...
Both curves adjusted to diferent scales looks something like this
