If anything, you also need to chainload to boot on haiku, which is free software. So no reason not to implement it.

Of course this is only a workaround I'm proposing, we should fix the installer to detect other OSs.
Just adding that we don't have any Guix bootloader entry field to
chainload into another bootloader, needed for some non-free system :)
this would need to be added as well.

I personally don't mind, and use my UEFI boot menu instead if I want to
boot into said non-free OS.

Best,
