First class support for soft links?

[Nuhvi]

Cool URIs don't change https://www.w3.org/Provider/Style/URI.html, the data store then should help users keep their URIs stable while keeping maintenance cost cheap.

1. When a user needs to share something on a public repo, it should be a soft link to where they usually keep and edit the file.
2. If the target file moves, should the soft link be updated? We have the privilege of servers being able to do that on behalf of the user, but should they?
3. How should a soft link to a private repo work? What if the target file was in a public repo, that was made private afterwards? should the server keep track of these softlinks and just duplicate and sync them?
