Why is there no method to InsertPoleAfter for GeomBSplineCurve

Poles can be added by InsertKnot with using the parametric space of curve. The reversed inserting will not have enough information about the parametric or if need to calculate will require some approximation issues (detecting the parametric value from point).

Can we use InsertKnot to insert the last point
To extend the BSpline with out of parametric space, you can use GeomConvert_CompCurveToBSplineCurve
