Yeah, I didn't have a good name thought up for this - IntentionallyZero might
be good, though even the word "Intentional" I'm not 100% on. Long run, the goal
is to split this category into different subcategories as you suggested, but
only at the point where there is some meaning to separating them - until then I
felt it would be premature to try to assign categories, since it's not fully
clear what they would be.
