I agree.  The ACA issue may be important, but it's not the point here.

Targets should report everything they can using transport-independent
mechanisms.  The task is a class-driver <-> LUN exchange, and status
should return in the same layer.  In other words, if you had a storage
array that reported errors in some way on ||SCSI and FCP, it will
(want to) do the same on iSCSI.
