As others have stated, there is more reliance in modern lens design on software corrected distortion and vignetting, making it possible to create zooms with longer ranges that are still very sharp in the center. If not, we would remain restricted to 2-3x zooms with corrected lenses. If that's the sacrifice we have to make (the slightly softer corners in modern lenses) then personally I am OK with that. There's no free lunch as they say.

One thing that i don't get is all three lenses (the slow 12-60) have very similar uncorrected distortion on the wide and as well as very large vignetting.
