The backup server should have information about when a particular backup was made, it should be able to prune based on backup date without having the ability to read any of the data inside the backup.

This doesn't make any sense when the backups are deduplicated (or incremental). A given file/block/whatever unit of data isn't uniquely associated with a single backup.
I assume the backups are incremental, so you cannot just toss old encrypted files without losing backed up files.
Worse, it's deduplicated, using a similar algorithm to git. You can forget old backups and theoretically that could be done without decrypting but deleting the actual data will require a decrypt.
