For the most part I agree, but if you ask "suppose I want [a conjunction of deprecated outcomes]" then it is possible that something tending towards one of these deprecations may protect against another. For example, hiding information so that it is not queryable may make testing and certain modifications more difficult, but encourage heavy coupling, which in turn makes a program hard to reason about and therefore also inscrutable - and thus, one further step removed, harder to test and modify.
