> Add a CLI command that allows users to specify an age at which to prune
> metadata that hasn't been modified for an extended period of time. Since the
> primary use-case targeted at the moment is list consistency, it would make
> sense (especially when authoritative=false) to prune metadata that is
> expected to have become consistent a long time ago.
