This certainly seems true to some degree.  Varifocal lenses - zooms which 
change focus as focal length changes - can have good performance/price 
ratios.

However, one only has to look at the Zuiko 35-80/2.8 to see that you can 
have a non-rotating front ring, fixed aperture, all metal/glass 
construction and true zooming and yet also top performance.

I think the main thing really achieved by not incorporating such features 
is a cost saving to the manufacturer.
