A simple one-time forwarding-configuration file pointing to the /boot volume UUID, permits configuration files to be written somewhere on /boot, which can then be md raid1 or btrfs raid1 based. Boot is made more resilient whether single or multiple disk. This works today on BIOS, but not on UEFI.

Speak for yourself.  libguestfs uses /boot/vmlinuz, as do other
packages, as does anyone wanting to see how the kernel was configured,
or to look at or change grub configuration, and so on.
