Ah... Yes.. Clipping
Sorry, I'm a little bit tired from a few parallel projects.
But, nevertheless, how about this as a new feature? So if the segment is out of the Spline/Distance range to be affected as it will be with Clipping Spline.
I just try to do some nesting and this type of behavior would be just right for me so I do not have to add Null at the end or Limit the End side to cut out the extended segment.
