FWIW, I used this partition layout for years, including on Guix systems,
and it worked fine. Long ago, bootloaders were only able to access the
first 8 GB or so of the disk, because of limitations in the old INT 13h
BIOS interface. Maybe this is still an issue on some ancient machines,
but I tend to use older hardware (my best laptop is ~11 years old, and
that's typical for me) and I've not had this issue in recent memory.
The only reason I started using a separate boot partition again is
because I now encrypt my root partition.
