+ - Drop the a{sv} per https://bugzilla.gnome.org/show_bug.cgi?id=673012

+ - Optional non-object metadata; e.g., "detached" GPG signatures which
+ are in the same file (to avoid double HTTP requests)

* Hybrid SSL pull (fetch refs over SSL, content via plain HTTP)
* ostree-commit: multithreaded/async (basically compute sha256 in parallel)
