People say that interchangeable superzoom ("travel") lenses can't manage good sharpness, yet superzoom compacts do just fine in terms of sharpness. Why is that?

smaller sensors being easer to design lenses for

But why?

Small sensors ==> small glass.  Large sensors ==> large glass.  It's much more expensive to make a superzoom lens for a large sensor because the image circle must project a larger image onto the sensor.  It requires a lot more glass.
