They do want it. We are working on it. We have a TierII emissions level pump line nozzle engine in a D9R bound for the Russian and possibly China and India market without any electronics and can run on really poor quality fuel. It's not Tier IV level of clean but it gets to where it does without any electronics. The world is slowly demanding cleaner air, cleaner fuels.
One of the biggest challenges to getting a diesel to very low soot levels is fuel quality and cleanliness. You have to raise injection pressure to reduce soot or raise cylinder pressure and temps. The downside to just raising cylinder pressure is a tradeoff in NOx emissions. Decrease particulates, increase NOX. The other knob that can be turned is injection pressure. To raise injection pressure requires tighter clearances in pumps and injectors. Clearances so tight that the dirt and debris in less regulated countries (LRC) cause premature fuel system failures. You can only have so many filters on an engine and they are only so effective at removing debris. No one wants to replace 6-8 filters to last 200-250 hours.
If you get into electronic controls on injectors you can do some rate shaping on fuel delivery and multiple shots to improve combustion efficiency and reduce emissions.
It's not going to happen overnight. The responsibility does not lie solely on engine manufacturers. The infrastructure in fuel refining and handling needs to improve to meet the needs of today's engines. As information and technology spreads through the developing countries and computer skills and ability to transmit information over internet becomes available they can begin using electronic control engines.
If you were to take a Tier IV engine off the end of the production line and take it to China and burn their fuel it wouldn't likely make it to 10% of desired rebuild life. Problems with fuel system and aftertreatment would be constant.

Today's Featured Article - Field Modifications (Sins of the Farmer) - by Staff. Picture a new Chevrolet driving down the street without it's grill, right fender and trunk lid. Imagine a crude hole made in the hood to accommodate a new taller air cleaner, the fender wells cut away to make way for larger tires, and half of a sliding glass door used to replace the windshield. Top that off with an old set of '36 Ford headlight shells bolted to the hood. Pretty unlikely for a car... but for a tractor, this is pretty normal. It seems that more often than not they a
