Curve transformation

There is an issue with transforming Geom_Line.

In theory, having a curve C, transform T, and transformed curve CT (CT = C->Transfored(T)), the following should be true:

T(C(U)) == CT(U)

However, in OCCT, this is not true for some curves (Geom_Line, for example) if T has a scaling component.

Is there any way to fix this?

PS. I see there is a method TransformedParameter, but not all algorithms (if any) use this method, and transform is not stored with the curve.
