Clearly not true:

$ sudo -i
root at bella:~# echo $SUDO_USER

As for what you might use it for, I can imagine countless situations. Say
you want to install a product with an "initial user" - who better to make
the initial user than the actual person who does the install, who clearly
has the privilege to set themselves up, anyway, and is also the only
account you can immediately tell ever gets used.

Karl, don't automatically assume the poster doesn't have a clue.
