Even though aws supports UEFI, many vps providers do not(Vultr and
Linode are some examples). But having a soft corner for Systemd-boot
and UEFI in general, I think there could be a middle ground. I believe
most BIOSes can boot GPT formated disk although there are few that can
not and I believe windows never supported this config. But since most
of the remaining consumers which real need this configs are VPSes which
generaly do not dual boot with windows. Also we can drop support for
all bios only bootloader as grub is good enough here.
If there is a way to push these companies to to switch to UEFI based VM
, that should be done. But removing all other bios config except for
bios + grub + gpt could be a fesible starting point.
