The BIOS provides block device access at sector level, so the boot

With UEFI much more functionality is provided by the firmware and there
is little reason for a bootloader to have tons of drivers. With the
exception of filesystem drivers in case you want boot from something !=
vfat. But even that should ideally be implemented as uefi driver not as
grub2 module.
FWIW, there seem to be UEFI driver for btrfs, ZFS, XFS and others:
