There is currently one draft (draft-ietf-hip-reload-instance-01) that 
uses this extension and defines in which cases the extension should be 
used. We believe that the Via extension can be useful in many contexts 
and therefore did not want to restrict its use cases too much but rather 
let the drafts using the extension define when and how to use the extension.
