Because detecting modifiers with UEFI is iffy and with
serial consoles is outright impossible.
I think that, if we have a serial console, we should have a minimum
250ms delay or so such that, if I hold down a key, I get a grub menu.
(Does UEFI buffer keystrokes? It might be sufficient to just check
*once* for buffered keystrokes.) On systems where I have a serial
console, I want to be able to rescue the system, full stop.
On UEFI, we should at least try, I think. And checking once for
buffered keystrokes would be really nice too.
