How we map that ATA spec into SCSI remains an open question.
Arguably we may prefer a mapping that gives us 512 bytes/LBA while
informing plug 'n play that read/write of larger aligned quantities may
complete significantly (like 100X) faster.
Already t10.org PDT x05 on paper says bytes/LBA is fixed at 2 KiB,
except for non-default modes, yes? So now likewise t10.org, moving in
the direction of modeling reality more accurately, might say this for
