Actually, it is/was a SCSI problem. The short version being that it is/was easier to hotplug an entire HBA rather than an individual device. That is being changed in 2.5 right now. usb-storage used an HBA-per-device, while SBP2 uses a single HBA.
Of course, all this is being changed right now in 2.5.x
