Interesting idea, does this stub bootloader already exist, or is it
something someone would need to write? (Either way I think it's likely
too late for Jessie, but perhaps something to think about for Stretch)

I'd also have some worries about packages installing to /boot/EFI since
that is by definition going to be a VFAT filesystem and I'm not
confident that dpkg will work fully/safely without all the POSIX-ish
semantics (hardlinks, atomic updates and the like), might want to handle
that by installing via the postinst instead of shipping in /boot/EFI.
