Some Linux distributions use the

This causes problems when starting a disk image taken from an existing physical 
server under qemu,
because when running under qemu name-of-disk-model is always "QEMU HARDDISK"
This patch introduces a model=s option which in combination with the existing 
serial=s option can be used to
fake the disk the operating system was previously on, allowing the OS to boot 
properly.

At first glance:

1. IDE only, scsi-disk is missing.

Correct.
IDE support is easy.

Adding SCSI support is more complicated, because "model" and "serial" are not the only factors that can make up a /dev/disk/by-id link
Could be a combination of 3 fields: vendor, model and serial.
But could also be based on another unique ascii or binary identifier provided by the drive through Vital Product Data page 83h.
