Proposed:
To the ConvertPts node, add two more Modes,
InterpCurves U, and InterpCurves V.

I tried out modifying the factory 'curve' to 'interpcurve', in two places in the points.js code, and the curves changed their mode...
Caused my project demo to have the curves go through points, but interpcurve(s) are supposed to be wigglier...
Would need to duplicate two sections of code to add the two interpcurve modes, and keep the curve modes...



Also added "e" and "f" inputs to the mathPts node, by modifying ~a dozen lines of code. (But they may not be needed...)
Seemed to work, but I may have overlooked something, in my ignorance.

Maybe I'll make a new version for the points2 extension category...
