I think a large part of the reason While I agree with your points, I'd observe that probably the biggest reason for sticking to something like that is risk mitigation. These types of projects tend to be so expensive, time consuming and risky enough for other reasons that nobody wants to get to just in front of the production delivery and discover that the scheduler isn't going to handle the job & all the code needs to be redone. (Especially if your scheduler is non-deterministic, you can discover major fundamental flaws as you bring in the very last pieces and it starts to fall apart.) I succeeded in using a tasking scheduler on a rocket project and it did present a change in mentality for the engine experts, but it did end up working very well. Still, it was a *hard* sell because of the risk.
