I assume that PG, after all his bashing of the college application process, is very careful about not giving the wrappings more weight than the applicant. So hints like these wouldn't be worth much. All of these points are really obvious anyway, the kind of things you would consider when writing any important text.
The wrappings are what exposes how good (or bad) the applicant is. Thinking that your natural wonderfulness will be obvious no matter how you fill out your application sets yourself up for failure.
