Even in black and white images, some people enjoy a falloff or darkening toward the corners, some do not. In architectural photography, what is acceptable in a personal creative exercise might not be under contract to the designer, who might want a more objective rendering better suited for publication or his own portfolio.
Then you've got technical issues especially in color, like when falloff leads to color crossover shifts. I've even employed that error deliberately a few times for creative effect. But most of the time, I don't want it. But in black and white itself, some people reach a point on the characteristic curve where the film ceases to respond in a linear fashion, for better or worse, esthetically. The point in having tools like center filters is to understand what they're for, and when you need to use them. People who go around saying they're unnecessary for this or that genre, or this and that kind of film don't speak for everyone.
