They can just make it a point revision or a standardised extension. There is no point in supporting this command on something like a hard disk, so it would always have to be optional anyway. It's quite possible the SATA 3 standard was too far along, or they wanted to make it an extension to SATA 2. So it's no big deal, but I'd still like to see this standardised ASAP as I think it will drive quite a bit of file system innovation.
