To prevent this I have a check when processing routing headers - when swapping the old destination and the new destination, it's an error if the new destination has smaller scope than the old destination. I think it's important that when a packet arrives at its final destination, if that destination is link-local then the receiving application can know that the packet originated on-link, and if the destination is site-local then the application can know that the packet originated within the site.
