That would require an alternative way to select the fundamental operation mode, though.
It seems impossible for more options on that dial to be simply hidden now and an alternative use of the dial in the future would imply an alternative way of selecting the fundamental operation mode (with the undesirable consequence that users would have to adapt to a new way of selecting the fundamental operation mode).
The current options are three modes of which one always needs to be active. It would not make sense for the dial to be in any (to be revealed) additional position. While theoretically possible -- pressing a modifier button could allow one to move out of "LV" without activating "stills" or "movie" mode -- more options would create an undesirable interaction paradigm and would destroy the ability to check with one glance which mode the camera is in (whether it is turned on or off).
Such a large dial seems overkill for selecting between three modes but unless it was initially planned to be used differently but then had to be retained, I guess the idea is that mode change is really given that importance. Personally, I'd replace the "lock/unlock" selector under the mode selection dial with a fundamental operation mode selector and find another way to permanently unlock the mode selector lock (or just omit the whole locking mechanism; A changed mode selector never ever tripped me up).
