I actually see the most sense in disabling FUA on devices with their own power supply for logical units which backing file is not (on) a removable device unless the removable device has some kind of lock (like CD-ROM's door).
Either way, I now see the point of having this option per-LUN.

Or even “nofua”. The other solution would be to change the meaning to the opposite (1 meaning that FUA is not ignored).
