I still think about the usefulness of this (particularly as my mind is back on representing feeds in IPLD)
The two use CID link types seem particularly useful there:
- The data linked with this CID is necessary for the complete use of the current node (preload is valuable; eg. images linked from an HTML page, or the content for a feed item)
- The data linked with this CID is a useful reference, and could be helpfully retrieved in advance if conditions are suitable (eg storage apace/network speed).
