Good question: it can cause unexpected glitches cause of a weird and unexpected sub-pixel behavior. This component aims to fix that with a GLSL re-implementation of the Ramp TOP. More in the video!
There is a glitch in TouchDesigner's Ramp TOP at half sub-pixel phase values where the gradient doesn't go from maximum to minimum in one pixel. This can cause glitches in instancing data and other cases as well (as shown in this video). My free RealRamp component produces a gradient jump from maximum back to minimum in one pixel/sample using GLSL. It is not a full replacement for Ramp TOP, but has the most common features of it --- glitch-free!!!
