My apologies, I assumed you read the rock rail thread when it was presented. You may often see me say or point to the fact that knowledge does not equal understanding. It is easy to see another company use the body mounts for rock rails and then make the assumption that is a good way to do things if you are just a designer and not a user first, installer, maintainer, and then a designer. Comparatively, it is the equivalent of an architect drawing up plans for stuff without ever swinging a hammer or cutting a board. Fortunately there is enough knowledge and understanding for architects to draw upon that they can mostly stay out of trouble. We don't have that in the offroad world, we have to learn stuff the hard way by using, fixing, doing, and then solving the problems that we have seen with the various designs over the years and why they do or don't work.
When a designer without offroad experience designs something and he is influenced by other designs, he will repeat the same mistake. If enough repeat that mistake, then those who don't understand (end user) will assume that the design is okay since so many do it that way.
A great example of that inverted T steering. It sucks, there is almost no way to make it not suck, and yet, it is common and oft touted as a great steering set up. What they should say is we can't do it any other way for a cheap steering set up and you the customer don't know any better anyway so buy our stuff.
