With the new addition of App Catalog scope called Site Collection App catalog, tenant administrators now has option to decide whether the SharePoint App will be made available for the entire tenant or scoped to specific Site Collection. This also can help organization to govern the permissions and scope it to limited site collection Apps only (For example you have a department called Sales and you give sales department administrator rights to manage apps for sales department site collection only).
