So the user would have to pin grub to its currently installed version
or completely refrain from upgrading the system, until the dead drive
gets replaced...
Frankly speaking, I don't like to inflict this on users, let alone
putting big warnings that say "do *not* upgrade grub, unless your RAID
array is completely working!". It looks very fragile: a system waiting
for a good opportunity to break, just because the user forgot to do
something and went on with the usual upgrades.

I still fail to see where's the problem with mounting multiple ESPs on
multiple /boot/efi* mount points: it seems to me that we would have
(almost) nothing to lose and everything to gain.
