Look closely and you will often see wheels in the air due to little droop, but the car still rolls. If you want less roll then raise your roll centre or change springs/anti roll bars.

The other factor that goes against this theory, is the suspension that becomes maxed out due lack of droop goes from being sprung weight, to being unsprung. This would affect the balance somewhat.

Lastly, you will only see changes in handling when the droop limit is reached. For example if all four wheels never leave the ground, then it makes no difference what your droop setting is.
