[Geonodes] Blender Tools ignore Curve Modifications

Image from Gyazo
In this example, I tried to use bezier curve with sine wave geonode modifier to drive Spline IK constraint (for snake like motion). Spline IK only follows the original curve. Same behavior observed with Curve modifier. Is it another oversight of geonode integration? Or there is the way to fix it?
