Filesystems have essentially the same problem, but collision is much less
likely, and "nested filesystems" are already handled like an oddity (via
loop command) for which responsibility is left to the user.

When you hide complexity from the user, the user doesn't generally care or
want to understand what this involves.  When we accept "(hd0,1)" from the
user, it implies we know what's the partition label in hd0, but reality is
that we're just guessing.  User, however, will expect things to "just work",
and if they fail will blame it on GRUB.  This is what I refer to when I
speak of burden.
