If the project is an industrial design project, or a branding related project, using an existing identity and it's associated set of rules gives a project structure. The request to use a known brand is usually part of the assignment from the teacher. This is like having a programming student code a Hangman game. The point of that, what you expect your student to get out of it, is totally different than an assignment where you say "design and program any game."
