Mini rant:
Form has touched on something worth noting: what percentage of the hunting population is even aware that things like proper recoil control, shot process etc even exist? Remember (or go read up on) the stories told about helping out at ranges prior to hunting season and how many examples of ignorance and/or laziness there were.
So indeed, the population here (and even at any of the other hunting forums etc) has to represent a very small portion of the overall population.
So with that in mind, the type of shooter that wants to be well informed is a small minority and is forced to contend with massive amounts of historical inertia in the world of shooting sports. To bring that home let's be honest and admit that a good percentage of THIS group struggled with the aesthetics of the rokstok initially (I did).
Another example, government red tape aside, how long has it taken for suppressors to gain momentum in the general shooting public? It sure seems like they have not really gained popularity until the last 5-10 years.
It's taken someone who works with people who's lives literally depend on proper function of a weapon system, along with willingness to push against the historical norm, to even open up the discussion on what should be different in this and other one areas of a weapon system.
So, all that to say, there is inertia, but innovation will come AND prove itself. It may take years but it wouldn't shock me at all if the design elements of the rokstok do work their way outside of this community.
