I didn't say it was. The point, which you're ignoring, is that when the driver knows the SAM nexus is terminated, it should call ->done() ASAP to inform the mid-layer of this condition, so the mid-layer model of the device interactions follows the SAM interactions as closely as possible. The API you want to introduce and the implementation of it in libata lie to the mid-layer and pretend the nexus still exists when the driver knows it doesn't ... what I'm saying is that I see no reason to do that.
