I think that there's a point in the fact that as technology is more and more available and cheap, people gets driven more by the technical thing rather than the creative/artistic thing. On the other hand, once you understand that is the man who should drive technology and not the opposite, it's nice to have the best possible technology (i.e. in this case the sharper lens) because you can always unsharpen a sharp lens (by defocusing, using shallow DoF, using tilting, blurring, putting special filters, using post-processing and whatever) to comply with your creative needs, but you cannot sharpen an unsharp lens. For some kinds of landscape or bird photography I actually like when I can count the leaves on far branches or the feathers.

 

In other words, once your brain is free from any technology-quality constraint (that is you're not obsessed by sharpness) it's good if technology doesn't impose any limit (that is, it's the sharpest possible).
