I think camless is where the engineering should focus. EGR becomes a matter of valve timing, you "miller" by leaving the exhaust valve open on the intake instead of pushing fuel/air out the intake valve. you can create ideal auto-ignition conditions (which the reformation here is a band aid for), deactivate cylinders, act like a compressor.

It too is "cheap and simple", a solenoid on a poppet being a glorified injector.

The reformation is interesting, as using the heat/expansion to help create torque is very co-generation like. But so many more variables and control complexity to compensate for having a camshaft. Sure some may pay more for it initially, not really sure what that has to do with engineering.
