DoF is perception.  Anything that changes the 'perceived' sharpness changes the DoF.

Some would have you believe that having to adapt to new technology is a workaround, but having adapted to old technology is photography.

That is where I feel you are wrong.  Maybe it is just symantecs, but DoF is not perception.

DoF may affect our perception of sharpness, but DoF itself is not perceived. DoF is a measureable range in which an object appears sharp, aka in focus.

DoF is created by the optics, its relation and distance to the sensor, and the aperture setting.  It can be changed from shallow to deep based on these factors.

If DoF was just perception, then wouldn't the amount of DoF perceived change from person to person despite all the constants above being the same?

Since perception is based on an individual's experience, that means that it could appear differently to someone else.  But Dof doesn't work that way, it is measureable and can be changed precisely.
