In theory, my-#acells claims to support a maximum of 4 cells. We don't use it though, and 128 bits would need special #ifdef handling for systems that don't have a native int128_t.
The case where we use 4 address cells (SCSI-3 variants) are for non-mappable buses, where we don't use the address for anything except the unit address. E.g., FC/AL with 64-bit WWN and 64-bit LUN.
