Checking user role is useful. For example, to style the back end with a
nice colour coding. It might be nice to have explicit has_cap() and
user_role_is() strict functions, but I'd rather that core settled on users
having only having one role before moving on to that. I think that is part
of the reason why developers use current_user_can() to check for role(s).
