I don't write huge systems with dozens of other people. So I can get away with basically "almost everything is a state machine" in C. The parts that are not a state machine are encoded patterns that are matched against in tables, for simple command parsing and the like ( for when an fsm is overkill ). The only cognitive load is generating test vectors, and I use scripting languages for that.
