I doubt the documentation for old_snapshot_threshold is going to be understood by many ordinary users. What is a "snapshot", first of all? Why would a snapshot be old? Why is that a problem? What can I do to avoid it? What are the circumstances in practice where this issue would arise, and what are the trade-offs? Where can I see existing snapshots and how old they are?
