I guess it is an open question together with a request… I was using it with mental ray using mia_photographic_exposure shader on the camera, surely enough not all the jobs required it and I turned the shader off on those occasions.
My interest is that since we have PBR seems odd not to have a photographic exposure approach on the camera and lights (yes, you can use IES but there is no consideration to use real life units)
In a way it is not just one feature...
hope it makes sense
