Even a great lens has a certain degree of decentering.
One of the local magazine used to measure the centering during their MTF test (at 40 lp/mm) and even the greatest of the greatest lenses had a centering variation of 5% ... brand new. And even the greatest of the greatest lenses should be used so these 5% will deteriorate.

I'm not suggesting we all build a sensor assuming we can feed it with diffraction limited f/1.4 optics, but my feel is we are able to extract more detail out of the better lenses already existing than we can with existing sensors. Personally, I am quite a cropper, so if that detail exists, I want it lens flaws or not. At least until Sigma invents an anti-gravity attachment for the 200-500/2.8. If the lens potential isn't there, you haven't really lost anything worse than a little capacity on your storage device.
