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.
