Yes, but in practice on systems which have serial interfaces and on
which it makes sense the console to be on a serial port, the UEFI
would offer the option; it surely doesn't offer it on my laptop as it
is pointless - there is no serial port.

Fixing this would allow for, say, repurposing old UEFI laptops with
serial ports to be used as servers; I have one of these with damaged
screen and partially non-functional AMG FirePro graphics card which
run -current and is used for regular system builds, pkgsrc and
qemu-nvmm; I'd be happy to remove the graphics completely and use the
serial port as a console, but it is a limited use case.
