Why no fixed aperture f/2.8 or f/4 zooms for mFT?

Lens dimensions seem to allow room?

Mostly folks have postulated that the lenses would necessarily grow in size, but I'm not sure this is necessarily the case. One reason I asked, is that a lot of the mFT lens diagrams seem to show quite a bit of unused space in the diameter of the lens if you compare the glass elements to the actual edges of the lens barrels.

eg. Oly 14-42

on the other hand, this lens is using is available diameter in order to acheive f/5.6 for its 150mm long end of the zoom

oly 14-150
