Right.  Now try to get the first disk to fail in such a way that it
remains visible to the BIOS but it no longer works, or no longer
serves the boot sector correctly, and see how that goes.  That's the
kind of scenario you might be willing to protect against, right?
Unfortunately, in this case, it won't renumber the disks, and the
system won't boot up.

It does.  This is exactly what you're tell grub when you change the
device mapping.
