If the oil passages are too narrow, then like I said before, why would it work fine for a certain random time then suddenly fail. And if it debree, gosh I gotta say how could something like loose casting flash not get caught at some point in the factory. All three possibilities seem unlikely when taking into account the "clean" factories that parts are built/assembled in.
The sensor idea is what seems most likely as I see electronics having a higher probability of failure as compared to something mechanical. Its hard to say as we're all just making educated speculations.
But hey, I could be completely wrong...

This is my best guess based on everything I've read. I've spent a lot of time working on cars and have done internal engine work in the past but I'm not an engineer.
The sensors are the most accessible components of everything they're replacing. If it was just electronics they wouldn't be taking apart the timing covers to get at those other components. I feel this has a mechanical root cause of some kind.
