Discussing corner sharpness with a fellow photography enthusiast i would compare to talking about the weather with a taxi driver.
The way I see it, the optical characteristics of a lens are indisputably important. All the charts and graphs and measurements help us compare and choose the lens that corresponds our needs. But deciding only on the charts can sometimes bring nervousness and a whole sack of onions and who wants that in their background.
Also, they are completely useless when you are searching for a desired artistic aspect such as glowiness, softness or special characteristics of the out of focus areas. For that, looking for the exemplary photographs is essential, even though, post-processing nowadays can be very misleading.
Regarding the corner sharpness, I mean, whatever I decide to put in the exterior third of the picture, i don't want it all sharp and attention grabbing. I guess that macro photography, wide shots and architecture can be areas where corner sharpness is important.
Well, that's just my two cents.
In the end, knowing your gear and its limits well can bring you more than owning an excellent one.
