However, if you now also want to pass a different implementation of User which does not have a getDisplayName() method, the code will break.

This check marks access to variables or properties that have not been declared yet. While PHP has no explicit notion of declaring a variable, accessing it before a value is assigned to it is most likely a bug. Loading history...
