I don't expect to live long enough to see grub2-efi no longer supported.

It's neither KISS nor green, having bootloaders on every installation in
multiboot environments. Multiple bootloaders offer an unnecessary avenue for a
spontaneous appearance of some bug that causes a heap of hurt and lost time fo
fix, meanwhile wasting bandwidth and media write cycles.

Mine are not just PCs, but also, in a fashion, archives. Many installations are
kept bootable well beyond their support lives, e.g.:
# lsblk -o NAME,LABEL,MOUNTPOINT
NAME    LABEL        MOUNTPOINT

These are all pleasurably booting from 13.1's grub-0.97-194.1.2 with
penguin=100 gfxboot, same as my numerous other PCs that continue legacy
booting. What ain't broke don't need fixin. :) My UEFI's all boot via TW's EFI
grub, though with a much less attractive and convenient grub menu.
