Application clients should send ATA PASS-THROUGH (16) and never the 12 byte version to ATAPI devices behind a SAT bridge, whose opcode is interpreted as BLANK (as pointed out by Doug), and BLANK executed.

That's a nice self-proclamation.
Got a pointer to a SAT or ATA/SATA standard that says it for real?
If you think this is a "self-proclamation" and want a spec to spell it out, then go ahead and send ATA PT 12 to ATAPI devices behind a SAT bridge. Just make sure there is no RW media in the device. :-)
The problem with that statement (above), becomes.. what to use
for the initial IDENTIFY request, before the type of device is known?
The statement above tells you: use ATA PT 16.
