GRUB2, which is a UEFI bootloader as well, is a far superior bootloader to 
systemd-bloat, and it supports usecases that are supported by Anaconda (the 
Fedora installer framework) that systemd-bloat doesn't, as addressed elsewhere 
in this thread by myself and several others. There is no way that supporting 
BIOS can be a cause for UEFI feature development being "held back". It's got 
nothing to do with UEFI stuff.
