I recall something of the opposite - a long time ago, we had to add a
variety of "safety" features to a product to fulfil a customer's safety
/ reliability checklist, without regard to how realistic the failure
scenarios were and without spending time and money on analysis.  The
result was, IMHO, lower reliability because it was more likely for the
extra monitoring and checking hardware and software to fail than for the
original functional stuff to fail.  Many of these extra checks were in
themselves impossible to test.

I've seen the code. In places there was an 8 level indentation
caused by if's switches and loops.

The advantage of a state machine is that it forces people to know the
state of the system.
