Deprecate secondary storage
I think the "secondary storage" feature has not been needed for a long time. Disk space is cheap enough so that files that are uploaded to BASE can easily be stored in the "primary" storage. For very large files it is porbably better to not upload the files to BASE in the first place, but instead use an "external storage" solution.
The first step is to deprecate all functionality related to secondary storage. In a future release, the functionality will be removed completely.
