If one never uses a shift lens and just relies on the Skew 
transformation, then there will be a sharpness loss in strecched areas 
over that of the photograph which employed a shift lens and no Skew 
transformation, or perhaps used Skew to tweak a minor correction from a 
shift lens which wasn't a perfect correction.

Architecture isn't the only subject Skew is good for.  Start looking at 
any shot with a wide angle lens in which the camera was tipped up or 
down and the skewing will be apparent. It is rampant in landscape grab 
and 35mm shots. Most trees grow straight, but they don't come out that 
way when the camera is angled.
