That looks like the sensible thing to do. Thanks for pointer.

Going forward, I will solicite more feedback from scsi developers
so NVMe's external attributes better align with storage that already
solved our issues. I agree with Christoph that we never should have
relied on SCSI translations for NVMe, but we don't want to reinvent
generic solutions either.
