Why so little in body image stabilization?

Of course it doesn't, but that isn't necessary either. Again, just look at how Minolta/Sony did it. If anything I get the impression that those users usually think that the IBIS implementation is an advantage, not a disadvantage.

If you are using a stabilized lens then you can just turn off the IBIS and use the in lens stabilization instead if you want a stabilized OVF.
