Does not apply to D1 of course, but Delta has made a marketing decision to offer upgrades to it's frequent flyers. My past and future purchasing decisions are partially driven by this benefit. So while I may not be buying F on every flight, I have an expectation of a chance to be in F on every flight (where it applies).
