How, exactly, is it silly? Or prepubescent? (The concept of sexualization being prepubescent is a nearly oxymoronic postulate in the first place.) The model is altered in physically impossible ways purely to exaggerate its sexual characteristics, rather than being portrayed in realistic fashion. That's practically the definition of sexualization. Does sexualization have absolutely no place? I don't think anyone would argue that. However, it is at best distracting, at worst harmful when it's used in inappropriate situations. There's no reason for a model in a tech demo to have (extremely) exaggerated sexual characteristics, and there are plenty of reasons not to - distraction from the main purpose, possibly making women feel alienated or objectified, and sparking off-topic discussions such as this one in a thread that should only have to discuss the game engine, to name a few. If it were simply an attractive or buxom model, I'd have little or no problem - it's the blatant, extreme, and pointless sexualization (without going into detail, none of the sexual characteristics of the model are even close to possible in a real human being), that is the problem.
