I'm far from a GRUB expert...

Apparently, the terminal input and output devices default to the
"platform's native terminal {input,output}":

Yes, that is a potential use case. For example, I have a system based on
an embedded system-on-a-chip that includes a GPU, but no physical video
ports; I must use the serial port.

I also have this use case on a laptop as a consequence of
<https://bugs.gnu.org/24948>.

For both of those systems, I've been using a different patch that
has the same effect on the generated grub.cfg.

Perhaps instead of a graphical? toggle, we could expose the different
values of GRUB_TERMINAL_OUTPUT and GRUB_TERMINAL_INPUT:
