Shutters with an efficiency between 75% and 50% just look more natural, from my experience.
The stuff proposed in this papers made it into blockbuster VFX production renderers ca. 2005 (3Delight) and 2007 (Pixar's PhotorRealistic RenderMan).
There is no information available on what full CG features use this. However, when you look at a still frame that exhibits heavy motion blur in isolation, you can usually tell right away if a perfect of imperfect shutter model was used.
The latter looks smoother/more natural.
As far as VFX in live action films go: it makes sense to match the virtual shutter to the one of the camera that was used to shoot the footage the VFX need to be integrated with.
The high end offline rendering plug-in, my company produces, has a setting for this.
The default we use (and that most of our customers leave untouched, I believe) is 75% shutter efficiency.
