You could be right. I'm not a professional market researcher. However, I'm guessing that neither are you. SE, on the other hand, doubtless has actual professionals working on this very problem - and those professionals have advised SE to use this marketing strategy.

We can armchair about it all we like on the forums. It costs us nothing to do so. You can bet, though, that these professionals take their research very seriously, and while they may not always be right, their careers are on the line if they screw up too badly or too often! I'm willing to bet that SE has done the research, and decided that marketing these things as extras to other products is making the company more money that simply putting the extras up on the Mog Station would.
