Cropping already occurs, it just happens before image capture. By capturing the entire available scene, the photographer gets to decide after the fact whether it's landscape, portrait, square or oval.
The reasoning is similar to JPEG capture vs. raw with JPEG conversion: if you start with JPEG capture you have limited your data up front. If you capture raw you give yourself more to work with later, even though you will need to do some kind of post-processing.
If you're thinking "I don't want to apply manual cropping to thousands of photos," consider that the software that supports this camera will have features to make this easier.
In short, no, I don't want vignetting, I just want to have maximum data, and never have to rotate my camera to change orientation.
To be honest, though, this is just hypothetical for me since I could not afford $8k for a body.
