Historically this didn't work with any supported qemu version as we don't set the alias of the device, and thus qemu uses a different alias resulting in a failure to startup the VM:
internal error: unable to execute QEMU command 'block_set_io_throttle': Device 'drive-sd-disk0' not found
Refuse setting throttling as this is unlikely to be needed and proper fix requires using -device instead of -drive if=sd.
Note that this was broken when I moved the setup of throttling as a command at startup for blockdev integration quite a while ago. Until then throttling was passed as arguments for -drive.
