This is confusing then. If the folders aren't empty how would the move delete them? You'd either have to run rclone delete and then rclone rmdirs or you'd need to just run rclone purge and the entire path will be removed. Thats how it works as of now. I'd argue that it would be nice to have a flag to leave the root directory (maybe an enhancement) or to have a flag to have rclone delete also remove the directories in one go (which is probably better actually).
