This is one of the things that changed when we moved from SATA to NVME. SATA has only a few "in flight" instructions and NVME does 64k.

Begs a question though: are there any NVME "spinny rust" disks?

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.
