Are there efforts by the imperium to industrialise it's feudal and feral worlds An industrialized society will always have the means to produce more goods and extract more resources than a feudal one and while charging horsemen into a horde of orks seems pretty funny, a chimera will almost always do a better job. And while I know the imperiums ressources are spread out thin and the imperium doesn't usually meddle in the internal affairs of their world (unless the are suspicions of heresy) what's the cost of sending a couple tech-priests to a relatively politically stable and loyal feudal world to act as advisor's to kickstart the process of industrialisation over a couple of generations. It's a small cost to pay and the reward would be a much more productive world that can produce a lot more ressources and men (Because the industrialisation of agriculture will allow to feed much more people) to the imperium.
