Simplification can exclude points with color stops

Polyline simplification can exclude points with valuable z-values. For example, I have several points with non zero valuable z-values which are placed exactly on one segment or their respective segments angles are the same or close to it. Imagine a track with 4 points, 2 middle points with z-value data lying close or exactly on one segment (has the same segmentStart - segmentEnd angle).
In this case color data is lost and no color stops except one is rendered.

It would be great if this awesome plugin could handle this case. I.e. not simplify sibling non zero z-value points.
