Unfortunately it can’t, because there are no UUIDs (that I know of) to
identify drives.

However, as the manual vaguely suggests (too vaguely I admit), you can
use a GRUB device identifier such as “(hd0)”.  This is stable across
reboot, AIUI.  I’ve never tried it but if you can confirm that it works
this way, we could/should update the documentation to propose that.
