grub-install simply looks for /boot/efi, /boot/EFI and is using root
directory as last resort if it is FAT. That's all. I would not call
this "automatic" - someone has to mount /boot/efi first and this is
manual step.

I think this is task for higher level system configuration tools - to
decide or ask user which partitions are boot partitions and where
bootloader has to be installed. Right now you designate filesystem to
be mounted as /boot/efi during installation. Manually. In future you
may allocate multiple partitions. One just need to come up with sane
scheme to name them :)

And this is not really GRUB2 specific. I had the same question recently
about RHEL6 on UEFI system and you can do it with elilo as well. You
need some higher-level framework to keep content of multiple ESPs in
sync.
