Does AHCI support new style TCQ (NCQ?) for ATAPI devices? If not, why not?
Are there any other reasons why new style TCQ (NCQ?) can not be supported for ATAPI devices (other than there needs to be a new variation of the PACKET command, probably just another bit in the PACKET Features register) to say use new style TCQ (NCQ?)?
Does this first require action/approval of the SATA "secret society" before T13 can discuss it?

FWIW AHCI doc is public, and is at http://www.intel.com/technology/serialata/pdf/rev1_0.pdf
SATA docs are also public, at www.serialata.org, though obviously all discussion of the docs occurred in the secret society. :)
