For the record, Intel was okay with making SCSI a separate config option,
but I was pretty clear about our wish to let it default to 'Y', which
didn't happen. :)

To be fair, NVMe's SCSI translation is a bit of a kludge, and we have
better ways to get device identification now. Specifically, the block
device provides 'ATTR{wwid}' available to all NVMe namespaces in existing
kernel releases.
