They don't want to make an image circle larger than it needs to be.
The smaller the image circle the better the other specs are going to be;
resolution, contrast.

And you don't want a bunch of light bouching around in a camera.

The shift lenes made for 35mm camrea will have of course a slightly larger
image circle to allow for moments. But slightly lower other specs.
