In fact, SCSI should make a few things easier, because the notion of host+bus topology is already present, and notion of messaging is already present, so you don't have to recreate that in a Xen block device infrastructure.
Another benefit of SCSI: when an IBM hypervisor in the Linux kernel switched to SCSI, that allowed them to replace several drivers (virt disk, virt cdrom, virt floppy?) with a single virt-SCSI driver.
