With all of Apple whizdoodling why can't they fit the iPhone 6/6s/7 Plus camera in the 6/6s/7?

I agree with pRICE, there is no reason that they couldn't expand the lineup by two, have a 7 and 7+ differentiated only by screen size, and a 7 and 7+ Premium edition with higher end features like the dual camera.

Or at least a 7 Premium with the higher-end features like the camera.

Seems obvious
The +models are larger than the nonplus models, which leaves more room to relocate some of the inners and make room for the 2nd camera in the 7.
