Funny that Klaus reviewed all previous lenses with Nex-5 (not with 5N). He even reviewed Nex-5 as a camera (with higher resolution score than anything else APSC that he ever reviewed). He never mentioned there was an "issue".
There is this reviewer http://erphotoreview.com/wordpress/
who tested several lenses with Nex-3. Then he bought 5N, and after some tests, he returned 5N because he claimed there was no difference in corner performance. Other people have claimed that they see a difference, but it's not clear if that applies to all lenses or certain rangefinder lenses.
My prediction is that if Klaus were to test, say the E-mount 50mm F1.8, on Nex-5N, the graphs would look "relatively" better (compared to the center on 5N). That is, the corner performance would be the same (not better) as Nex-7, but the center resolution would be lower on 5N than Nex-7. So overall the graph might look more uniform on 5N, but that doesn't mean 5N magically will show more detail in corners than Nex-7. I don't believe it will, and and I will put my money on that prediction.

As I have shown with examples, earlier in this thread, the CZ85mm f1.4 is better, is better on the 5n than on the 7, in absolute resolution (in the corners). This is certainly not a rangefinder camera. In general, this is the only lens I really see this with. A 1.4 lens that is sharp in the corner is rather unusual, so there are not many lenses that can show this behavior.
