::It's the balance between absolute cost and value I suppose. This actually also illustrates how much vested interest there is in selling this thing to people, which connects very well to all the discussions on sales pitches. This post is relevant, not "forum" because it contributes to the case for taking the most neutral tone possible, and not simply propagating various claims by these vested interests, so "plane is designed with xxx in mind, hence bell A and whistle B" rather than "this plane can xxx very well using bell A and whistle B". We might be discussing cost right NOW, but in fact mission elements can also be very sensitive to developments, and that needs to be kept in sight by the article in order not to simply feed the grandiose claims of whoever, to the layman reading the article.
