Why does a leaf shutter mitigate the absense of IBIS? IBIS isn't design to handle the frequencies induced by shutter vibration - in fact shutter vibration is known to interfere with some stabilization implementations. IBIS is designed to reduce hand-holding motion, ie frequencies of human cyclical movements. Also, an EFCS is effective at eliminating shutter vibration.
You are correct that “shutter slap” and the vibrations/motion from hand-holding a camera are very different things.
Shutter slap is generally an issue when the camera is on the tripod and all other sources of vibration and motion blur have been eliminated — it is the one remaining issue (in most cases) that can be controlled. In the old days that was done with mirror lockup, but for the past decade or more as mirrorless cameras have taken over, EFCS has essentially eliminated it.
For handheld photography — which I’d wager is how this camera will mostly be used — shutter shock is not a significant issue and the real concern is motion produced by hand holding the camera. That is what IBIS deals with. (IBIS doesn’t really do much for shutter slap.) If one promise of the 100MP miniMF sensor is that it captures finer detail, then camera stability becomes rather important to realizing that potential benefit.
I suspect that the main benefit of the leaf shutter in this fixed lens camera is that it helped keep the camera/lens assembly as small as possible. (A secondary benefit fora few users — but probably not your typical buyer of this camera — has to do with flash sync.)
