Blender 2.8 Select Circle feedback

Why doesn’t Select Circle have the same mode options like Select Box and Select Lasso do? It seems to me like Select Circle could benefit from these optional modes as well rather than only the “Add” mode.

It is my understanding that previous versions of Blender allowed you to increase or decrease the Select Circle radius using the mouse scroll wheel whereas now it seems like that doesn’t work in Blender 2.8 and I have to change the radius from the slider at the top of the screen. Not the biggest issue, but I would prefer if there was a way to do this without having to mouse over to the that slider.
