It would be interesting--and visually useful--if  POV offered an "alternate"
type of focal blur, one that blurred the image only from the camera to the
object/point of interest, then kept the distance beyond that sharp. I'm
thinking along the lines of "hyperfocal distance" in a real camera lens,
but more extreme. I believe (and this is subjective, of course) that it
would help to make the blurring more realistic. As for outdoor scenes on a
bright and sunny day. It would seem to me that implementing such a blur
would *only* (?) require that image pixels "beyond" the point of  max
sharpness not be jittered. As it is now, pixels are jittered (equally?) in
*both* directions relative to the max sharpness point.
