That is unfortunate if true.  I've been studying cube efficiency and at 
the moment it seems to me that the information contained in those 
statistics is extremely valuable for understanding certain kinds of 
positions.  Introducing more support for those statistics would in my 
opinion be a very important feature.  Some way of saving them to a 
separate file (if not the .sgf file), for example, would be a good first 
step.

Another thing I noticed is that if I set up a cube decision (say), click 
on "Hint" and roll it out, and then go and customize the rollout by 
clicking the "..." tab (for example, increasing the number of trials) and 
then I click "Rollout" again, the "View Statistics" button disappears. 
In other words, if I do a 1296-game rollout I can "View Statistics" but if 
I then try to extend to (say) 5184 games, I can't "View Statistics" of the 
extended rollout.  It seems I have to set up all my rollout parameters 
correctly the first time around.  (As I type this, it occurs to me that 
this might be related to another bug that was apparently fixed last 
year, so maybe if I reinstall the new version of GNUBG this won't happen 
any more.)
