I'm not sure marketing alone is the culprit. I don't think most manufacturers are promoting this type of binding for inbounds use. With retail on touring gear is in the $2000+ range, I think sticker shock alone has a lot of people skiing their lightweight touring skis as a single quiver. I did it for a few seasons when I was living back east and only able to ski a few trips a year because I didn't have space or money or the ability to transport a bunch of gear. I have a friend who ripped his ions out of his skis a few weeks ago. Lucky the screws were the weak link and not his achilles I suppose.
