Isn't this a variation of the myth of the megapixel myth? Sure higher density sensors will magnify at pixel level any weakness, but the "big picture" flaw will be the same. A bad lens is still bad, but a great lens can get better if it would otherwise be held back by the sensor.

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.
