 This is the implementation: a feature, marked experimental, that allows the

-blobs are excluded, replaced with URIs. As noted in "Future work" below, the

 need for protocol changes, so only a small-scoped design is included here to
 form the MVP. For example, the following can be done:
 
- * On the server, more sophisticated means of excluding objects (e.g. by
-   specifying a commit to represent that commit and all objects that it
-   references).
  * On the client, resumption of clone. If a clone is interrupted, information
    could be recorded in the repository's config and a "clone-resume" command
