Well, TBH I think it's redundant information since libata (the Linux implementation, for our fair readers) already carries the data direction implicitly. I cannot see a case where the data direction is not available at all.
Vendor-specific & newly standard ops?
The data direction is _always_ provided by the user application creating the CDB / taskfile.
We can fully support vendor/future ops, without an explicit data direction in the CDB.
