I think the general answer will be No. A similar question is whether ide-floppy is superfluous and one can do everything via ide-scsi. Again I think the answer will be No. Indeed, ide-scsi uses the Packet command A0 of ATAPI to send SCSI command packets to the ATAPI device. But there is no reason to expect that all ATAPI commands are covered this way. The first example is already A1: IDENTIFY PACKET DEVICE. SCSI has INQUIRY, but that is not the same. I have some ancient patches to ide-floppy.c that allow one to switch an Iomega ZIP drive between large floppy and removable disk. I do not know of a way to send these same commands via ide-scsi.
