MouseWheelDetails isSmooth for vertical and horizontal scrolling

Feature Requests

My mx master (which is pretty much the most popular working mouse) has a vertical and horizontal scroll wheel. I can switch between smooth and normal mouse wheel scrolling on the vertical wheel, but juce always detects a smooth wheel, probably since the horizontal one is always smooth.

What speaks against a split into isVerticalSmooth and isHorizontalSmooth?
My usecase would be scrolling through comboboxes:

if (!isPopupActive() && e.eventComponent == this && wheelDelta != 0.0f)
            {
                if (wheel.isSmooth)
                {
                    mouseWheelAccumulator += wheelDelta * 20.0f;

                    while (mouseWheelAccumulator > 1.0f)
                    {
                        mouseWheelAccumulator -= 1.0f;
                        nudgeSelectedItem (-1);
                    }

                    while (mouseWheelAccumulator < -1.0f)
                    {
                        mouseWheelAccumulator += 1.0f;
                        nudgeSelectedItem (1);
                    }
                }
                else
                {
                    auto delta = wheel.isReversed ? wheelDelta : -1.f * wheelDelta;
                    if (delta > 0)
                        nudgeSelectedItem (1);
                    else
                        nudgeSelectedItem (-1);
                }
            }
            else
            {
                Component::mouseWheelMove (e, wheel);
            }
