I don't think it's that unusual.  Let's take an example.  We have 1 PATA
disk and 1 SATA disk, and are installing GNU/Linux in it.  We only have
one /boot partition (or directory in /).  Turns out we have no idea which
of the two disks the BIOS will want to use for boot.  So the safest option
is to grub-install in both.  A consequence of this is that one of the two
installs is cross-disk.

And (provided that UUIDs are used), this setup is _completely_ reliable and
there's no reason to prevent the user from doing it, IMHO.
