A bokeh is "fake" already - because the human eye doesn't produce one - at least none that you are aware of. ;-)

I, for one, have no fundamental issues with an artificial bokeh. Quality-wise it should easily surpass the "real" ones - e.g. no distorted highlights at the image borders (which I consider to be quite distracting really), perfectly even discs and no nisen bokeh. It should also be easily possible to add slight defects in order to avoid plastic looks.
