As many as you want could be added.  But there are already three ways to 
move between completions.  < and > are assigned by special-mode-map to 
beginning-of-buffer and end-of-buffer.  IMO changing the C-{fbnp} commands 
is not necessary, given that that moving around with their usual meaning 
makes sense.

I do, from time to time.  I'd be surprised if I were the only one, as I 
remember that it's something I already did during the first days I used 
Emacs.  When you see a window with lots of information appearing, is it 
not natural to enter that window and to move around?

C-x o.  Perhaps it would make sense to bind "o" for this, too.  And/or 
"Q".  WDYT?
