'Extrude Curve' node

It would be really great to have one, right now I'm having to subdivide a two-point curve once, then I move the mid point to the position of the last point and then I have to translate the last point to the desired position. It would be much easier to have an 'extrude curve' node so we would create a new segment from the last point that would follow either the tangent or a custom direction. Is there a reason why it doesn't exist or it simply hasn't been thought/released yet?

In this image, I have a horizontal line in the ground, from which I instanced the vertical poles, then I realized the instances, subdivided the curves, grabbed their mid-point and dislocated to the last point position, and then took the last point dislocated in an angle.

PS: it would be much more complicated to extrude after the 'curve to mesh' node, because you see that the pole get sheared ('skewed') before extrusion.
