Interference detection: why volume, not linear interference?

Long ago, when I ran an interference detection Solidworks would display the linear dimensions of the interference. Now it gives a volume of interference. I honestly can't imagine why it's useful to know that two parts have .0000063 cubic inches of interference!

This is yet another example of SW changing useful features to useless ones. Why is there not at least an option to display linear interference?
