It's also worth noting that in the last 50 years, the flash sync speed of shutters has gone from 1/60 to 1/200 or faster. A wee bit'o physics can show that faster shutters mean much much higher shutter shock -- 3X the sync speed creates 9X the shock.

Creating a shutter with a controllable curtain speed would let the photographer use a slow sync speed with much lower shock levels under conditions where shutter shock might be a problem. It may even be possible for the camera to analyze its internal accelerometer data and provide a "shutter-shock alert" after the picture so the photographer knows to inspect the image; switch to slow-sync mode or better secure the camera and lens; and retake the shot.
Great idea!

My K-1 with DFA*50 produce shutter shock blur from 1/200s - 1/320s and slower. It is worst at 1/160s and slower. I cannot use IBIS because it would be pointless to use DFA*50 then.
What do you mean, why would it be pointless?
