No, I don't see the mid-layer error thread handling of this ever going
away.
libata is simply being lazy: while the SCSI core continues to support
kicking the EH thread when sense is missing, it's preferred for libata
to reuse that infrastructure.
That makes the most sense ;-)
For libata it doesn't really matter, since it is _ATA_.
It matters quite a bit. One of the main reasons libata uses the SCSI
layer is for its infrastructure.
This is the same reason a couple RAID drivers use the SCSI layer. It
has nothing to do with SCSI-as-defined-by-T10, and more to do with the
fact that SCSI provides a robust queueing/EH/block interface infrastructure.
My long term plans include moving some of this not-SCSI-related
infrastructure from the SCSI layer to the block layer.
