Yes. As you know, near or far doesn't matter since the angular velocity on the sensor is the same and the net result is an effectively linear smear which can be usefully analyzed as a blur disk (circle of confusion) with the same parameters that affect depth of field (print size, degree of enlargement, visual acuity, viewing distance).
Yes, but it does matter for the "shooting bunnies" from a moving train scenario - what a despicable thing to do.
