I have my doubts that building on sd-boot and drop grub2 is going to fly.

One problem with sd-boot is that the kernels must stay on the ESP, which
can be a problem for dual-boot installs (where Fedora has to run with
the existing ESP and can't just create one which is big enouth).

Another problem is that grub2 covers more architectures than sd-boot.
What is the plan for armhfp, ppc64, s390x?

IMHO a better preparation for deprecating BIOS would be to make new
installs bootable with both BIOS and UEFI.  Which isn't hard at least
for the "[x] use all space" case where Fedora can partition the disk as
it pleases:  Use gpt.  Create a bios boot partition, install grun-pc
there.  Create a ESP partition, install grub-efi there.  Create a
partition for the /boot filesystem.  Have both grubs pick up BLS config
from /boot/loader.

take care,
  Gerd
