Right. That'd be what SATA 1.0a brings to the table.

Not in SATA 1.0a, no, that intentionally specified physical layer
only, simply carrying ATA and ATAPI commands. But SATA 1.1 (aka SATA
II) adds command queueing, SAF-TE, signal recovery / hot-swap (device
quiescence, comms state (stop/start/reset - whole state machine)),
async notification, etc.
The host controller interfaces tend to be far far nicer and more
modern too, from what i gather from Jeff Garzik's posts.
