The problem is that splines don't subdivide geometry; they merely
provide a mechanism for finding a point on a curve.

In other words, if I have a spline MySpline, then I could do:

MySpline(0.5)
MySpline(1/9)
MySpline(3.14159265358)

And all would return points.  Nowhere does the spline itself create a
list of points.

You seem to be thinking of a spline as a sort of vector array.  This is
not the case; it is a mathematical representation used to create a
curve.  We then take values from that curve for all sorts of reasons,
but what use we make of them is unrelated to the spline itself.
