I think the matter of whether perspective "distortion" is a Good Thing or a Bad Thing is largely subjective. My guess is that the person who coined the term "perspective distortion" considered it a Bad Thing. I think a better way to look at it is as "perspective control", in that in some cases, especially with extremely wide angle shots, the bending of what were straight lines can be so extreme that it draws the viewer's attention from the intended subject. And on the other hand perspective "distortion" can be used to the photographer's artistic advantage. Having control over the effect can only be a Good Thing. :-)

One of the things that a View Camera can do that I haven't
been able to duplicate in postprocessing (aside from the
ultra-high resolution inherent in large format film) is to
tilt the lens and film planes. I wonder if it's even
possible for software to correct poor focus at all. I
suppose not.

P.S. For a really striking example of the sharpness of large
format photography, go to the link above and click on the
