@CChoupi,

You are right but as has already been mentioned a few times the difference between the original Pongo ux (button_delete_route.zip) and the other ux (button_deleteroutewp.zip) is that the original ux is only available in the cockpit when the route end unlike the other ux that if there is a planned route, the button is shown in the cockpit and the user can delete the entire route or any waypoint at any time.
