Yes, very true. I can imagine user space apps sending SMP and what not to expanders/RAID devices/enclosures past expanders, to control the storage network. A sysfs representation of the discovery result could make this easy, since as you pointed out expanders are not SAS devices, and thus do not fit the linux-scsi HCTL space.
