Libata is a self admitted kludge.

/dev/sdx => scsi disk

Libata has stuck itself under the scsi disk driver, so you are right that not 
all scsi disks have a ata_host kludge, only the imposers should have one.

One path I have never chased is for an external usb connected drive.  Scsi 
commands are sent a across the usb bus so there is probably not any libata 
involvement.
