The point of making an f1.2 has always been to shoot at f1.4 f1.8 with the aberrations and vignetting mostly eliminated. If you do shoot wide open with them, it's almost always with the subject in the middle or one of the 1/3 lines so the vignette doesn't cover them. This is more than crop sensors can hope for, as their fastest lenses are equivalent to f1.8s wide open and soft as hell with a heavy vignette on top of it, and are often manual focus only.
Crop sensors do vignette about 1 stop less, even if the lens is "slow" wide open

Did you ever even notice any of this?
You probably didn't because good photographers always shoot f/8 at base ISO.
