Making a superzoom for a compact is easy, but for a DSLR, it's hard?

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?

If "just fine" is acceptable, be it distortion control, optical sharpness and aberrations, then it isn't a big deal for DSLRs either. I have Sigma 18-250, which 28-375mm (FF) equivalent, and quite good actually when stopped down a stop or two.

But, a part of consideration for an ILC (interchangeable lens camera) is that you don't need to compromise with a "one size fits all" solution, rather be free to get a variety of lenses suited for specific needs.

This is focal length distribution (FF equivalent) from 400+ images I recently took during a road trip (excludes dozens of images taken with an 8mm and a 50mm lens):

A vast majority of images were taken between 24-130mm (16mm - 90mm, APS-c), only a few at 320-380mm and very few in between.
