Everything seems to work fine without sd_resume(), so why is it needed?
Because not all disks spin up without being told to do so and like it or
not spinning disks up on resume is the default behavior.  As I wrote in
the other reply, it would be worthwhile to make it configurable.

Not even after they receive a read command? Ugh.

ATA disks are supposed to spin up, yes. SCSI disks require a command to tell them to spin up if they're in the "stopped" state.
