Dropping the "legacy BIOS" support is a horrible idea:
Not just there are a lot of "legacy BIOS" PCs, especially in a corporate world
where the upgrades are slower than in the domestic environments.
There are also a lot of really modern PCs running a coreboot firmware with a SeaBIOS
payload - which is a modern "legacy BIOS" written in C.
SeaBIOS has just 50k code lines: infinitely slimmer and much more efficient than a bloated
UEFI abomination, even a Tianocore opensource one.
UEFI is a "SystemD of a BIOS world", in a horrible way.
Well, if you'd drop a Legacy BIOS support, more of the coreboot opensource BIOS people
will move to the other distros,
hopefully those which don't have a SystemD security-vulnerable bloatware - for
example, Artix Linux, great user-friendly Arch without SystemD.
So please go ahead and drop "legacy BIOS" support, so there would be one more
reason for us to abandon Fedora with a SystemD hardcoded into it.
