I have several high resolution screens. I can see my BIOS boot text just fine. You're talking about a solution in search of a problem.
So do PC laptops that do UEFI boot since Windows 8.
It's not really problem on laptops, but more on desktops, especially if you have add-on cards that initialize themselves with custom UEFI addon. Or when you need to work in UEFI shell. Or when you use boot manager in text mode, like grub (but grub know how to switch modes, at least). Or miriad of other things, that fall outside of the happy path of bootloader booting the OS on fixed hardware.
