That and imagining that they will encounter situations similar to what is described in marketing hype.
Roadies also tend (many of them, anyway) to define rides by the climbing. Tri courses are typically mostly flat, and since you're always coming back to transition, weight spent on aero is worth it since you care about total time. The climbers (in what I read) only care how fast they get
up the mountain, and aero helping their speed down the other side isn't helpful.
