Indeed. Funny to see this article pop up now because I've been considering the purchase of a USB volume knob for this exact reason.

The Touch Bar volume control is almost right except it's too damn slow. Dragging the volume button works, but the control doesn't start for another 500ms. Try touching it and immediately swiping all the way left, the finger will leave the bar before the control opens. Sigh.
