Coming at it from another angle, we have historically made distributed systems manageable / 'verifiable' with RTOSs which give deterministic scheduling and locking primitives. We know that a task's max duration is its uninterrupted duration + max duration of all higher priority tasks which could pre-empt it, and so on. Deterministic pre-emptive scheduling and locking alone could be enough to prove a lot of invariants without full temporal logic, and writing code in 'RTOS logic' might be more natural for humans/LLMs than the more expressive and powerful alternatives.
