When I build a drive to the current revision of the SCSI spec, I don't know
the future holds for the Reserved fields.  By rejecting a command with a
bit or field set, I inform the initiator that I don't know how to do what is 
requested.  Initiators that care about data integrety understand this.

When a customer asks me to ignore the Reserved bit in a command, I can point to
the SCSI spec. and explain why the target rejected it.  If the customer insists
on User Friendly, I can set a special non complient mode.
