But what would prevent this system from being compromised?
Seems pretty easy for an adversary to "inject an exploit in these controllers" by paying a few of them to keep the knobs in the wrong position for a bit more time than strictly necessary, or to flip a switch earlier/later than ideal.
Auditing this is seems worse than checking the code for an old-style, non-networked, PLC.
