I presume this would need changes to the API described at `info
"(guix)Bootloader Configuration"` to generate each boot.cfg menu-entry
repeatedly with different boot options,

or it would need a custom copy of grub-bootloader with said changes to
boot.cfg generation,

or a new feature to, as you wrote, include multiple operating system
fields in the same image.

Anyway, I wouldn’t be implementing it.  I will close this bug report
in a few days.
