I could see that being totally valid after thinking about it for a second!
I imagine it as a new dimension growing “up” out of the X/Y plane (as burrowing into the ground would be going into “occupied” space, it’s forbidden). But “depth” does make that make more sense.
But in those cases, isn’t positive Z going “away” from you ? I.e. Into the ground ?
And in math classes this has always been described to me as adding “depth”.
