If we're talking about spiral housing for the final curve in rear derailleur housing, I've found it's really good ferrule the ends. There's a stepped ferrule to fit it into the frame braze-on, if present, and it does a lot of good in making the housing rigid at the derailleur body end. I wouldn't want any of those cut wire ends gouging into my vintage Campy part, after all, not to mention needing smooth, like-new shifting.
