Basically for doing sanity checks on the CAS, e.g. to detect if client code 
creates FSes but never adds them to any index.

We've hit a bug in one piece of software where some annotations were indexed an 
others not. The latter were still reachable in that case so I could implement 
the sanity check without this capability. But while doing so, I was wondering 
whether it was also possible to recover non-indexed FSes.
