My recollection is that NVMe had some features added specifically for hard drives. I don't know if anyone ever bothered making a hard drive that natively used NVMe over PCIe; the main goal was to enable NVMe over Fabrics to work with both solid state and spinning rust drives, so that it could fully replace iSCSI.
