I agree that it’s kind of odd that the letter U doesn’t even appear in the next, as it has indeed become kind of a convention to try to use the first letter but it’s even more important to avoid using commands that are hardwired in people’s mind to do something else. Cmd-D is usually Duplicate, Cmd-O is open, Cmd-S is save it’s often more annoying if you “override” those defaults than that it helps remembering the shortcut.
Plus, here’s another thought. It’s not that in Dutch, German or French, people get different keyboard shortcuts, so only English speaking people have traditionally had the advantage you’re describing…
