Fedora developers are debating the end of Legacy BIOS’s boot support for this Linux distribution, which only supports the benefits of UEFI-based installation.
Considering the change plan for Fedora 33 GRUB, if they just switch to UEFI-based systemd sd-boot, and Intel plans to end support for Legacy BIOS by 2020, and UEFI is already very common in x86_64 systems, then things will become easier. Fedora developers are discussing whether it is a good time to start phasing out support for Legacy BIOS now.
Of course, not everyone agrees that Fedora gives up the idea of supporting Legacy BIOS. Some users who used hardware from 2012 to 2013 expressed disappointment that they might not be able to use the new Fedora version on their UEFI-free hardware.
They also made another point. Even though most of the key components have been supporting UEFI-powered virtual machines for many years, some virtualization settings are still used by default or rely heavily on Legacy BIOS to boot.
There is no formal proposal to terminate Legacy BIOS support and only UEFI support, but the Fedora team has begun active discussions on this issue.
Considering that the deadline for system changes has passed, I believe that Fedora 33 will not give up support for Legacy BIOS later this year, but maybe next year or next year, we will see them give up their support for Legacy BIOS.
