This feature request probably is superseeded by the "Navigate route as track" feature in combination with the fact that every route already contains a lowres track to enable this feature.
Having said that, to copy a route as a track could be beneficial for sharing the track among users of third-party navigation systems from within the MyRouteApp planner (without export/import). Also it is a great tool for quickly comparing a route for changes, when they are getting old.
