What do we think about providing an actual example for the classic noSQL injection with MongoDB, as is demonstrated and documented in the tutorial?

Screenshot from A1 - Injection tutorial:

So while the tutorials show this example, the NodeGoat app actually implements the user login differently with:

usersCol.findOne({
            userName: userName
        }, validateUserDoc);

Do we possibly want to change the login to use the classic style as is documented or maybe provide another login screen just for the sake of demo'ing the example?
