Having the latter is often helpful to learn why the suggestion is actually not a mere "you could" but is a "you are better off doing it this way". Even though it is discouraged, people script using the Porcelain "git diff" command, and once users of such a configuration variable is used in Doron's fork of Git, those scripts will break for them. Using alias like you showed won't have such a problem.
