I suspect that's because you've never seen any of the new types in
practice.
0x70 is really the only sense type we process correctly: Fixed Format.
0x72 is the newer Descriptor Format. 0x71 and 0x73 are the Fixed and
Descriptor format deferred sense conditions.
We really only get deferred errors if the device has a cache that is set
to writeback, so we just hope never to see them...
I thought Doug had a proposal for unifying our view of Fixed vs
Descriptor sense formats?
