Having the ability to create a corridor without needing a vertical can be helpful when a project involves widening. With widening, I wouldn't need a profile along the CL, but instead it would be along the EOP. Point controls can be used to attach to geometry that is along the EOP, but I would still want the corridor to be based on the CL and not the EOP.
