As a user, when I'm implementing my own StorageAdapter, I find the parameters defined by the interface to be a bit limiting. Specifically, the uploadFile, downloadFile and deleteFile methods. In order to interface with my own backend, I need more information than just the filename or uri, I specifically need some of the information from the attachment record, including the additional columns I've defined.

For my own use case, I've resorted to stuffing any information I need to process the file to the filename of the record, which works - however this seems a bit hacky.

Is there any possibility of having this interface expanded to provide pass alone the attachment record?
