SketchFittedSpline's NurbsCurve3D.isRational is True even though all weights are 1.0

The subject can be quickly demonstrated by using the text command, Sketch.GeomInfo, on a Fit Point Spline created via the GUI.

 

Is this intentional, a bug, or ...?

 

Also, the rational property seems to propagate to the creation of some NurbSurfaces, such as an ExtrudeFeature made with a SketchFittedSpline.

I'm don't have much experience with NurbsCurve so I may be wrong but I think the isRational property indicates whether or not the curve was created as a rational curve, not whether or not the curve is actually rational.
