Tension/Stress and Velocity Map node for geometry nodes

-Tension Map node (Stress map Node)

-Velocity Map node

So could there be tension/stress map like this: blender.community/c/rightclickselect/zQfbbc/ in geometry nodes?

And velocity map like this: vimeo.com/141650974 (its vertex/point level velocity map - visualizing speed of vertex/point in weight map - so it need to calculate frame a-b distance change - "time" and length -> speed ) But Velocity Node.
