For enterprises that leverages Legal Holds at a very large scale (hundred of them or more) some would like a quicker snapshot to see which users are custodians under legal holds in their environment, and how much content is being affected (in GBs, without listing every individual piece) without running hundreds of legal holds reports individually to gather this data. A quick check like this would then allow them to decide which legal holds they need to run more granular reports on, saving time and resources
