Regarding the state of other zoned devices:

--device scsi-block should be able to pass through SCSI ZBC devices.

QEMU supports NVMe ZNS emulation for testing, but cannot pass through
zoned devices from the host yet. If you have an NVMe ZNS device you can
use VFIO PCI pass the entire NVMe PCI adapter through to the guest.
