I don't think it is a big issue, there just needs to be indentation
settings for different levels and some logic to handle it. In "GRUB CSS"
this could be something like:

menuitem {
   left: 0px;
}

menuitem indent1 {
   left: 10px;
}

meunitem indent2 {
   left: 20px;
}

And then add something like:
set menumode=outline
set menumode=hierarchical (or normal, default)

So end result would be something like this:

Windows (menuitem indent0 odd)
-- XP (menuitem indent1 even)
Linux (menuitem indent0 odd)
-- openSUSE (menuitem indent1 even)
---- 10.2 release (menuitem indent2 odd)
