I never saw such degradation in optics for minimum focus distance.

Here is a photo I took at 0.65m focus distance. This is not MFD.

The halo/vapor/softness effect is still noticable.

0.65m is still pretty close to MFD. Again, optical quality of a lot of lenses degrade when you focus this close.

Christopher Frost specifically checks lenses at MFD for this reason:
