You learn something new etc...

But I'm trying to figure out what difference this makes in
practice?

If you were targeting a German audience wouldn't you just test
against the German alphabet? After all you still have to expect 'grosse' 
which isn't English, so if you know to expect grosse
why not just test against große instead?

I think I'm missing something.
