I partly disagree; steganography is only useful when it’s possible for the outside / receiving system to detect and interpret the hidden messages, so if the messages are of a type that outside systems would identify, they can and should be detectable by the gating system as well.
That said, I’d be very interested in looking at formal guarantees that the outputs are minimally complex in some computationally tractable sense, or something similar—it definitely seems like something that @davidad would want to consider.
there’s steganography, you’d need to limit total bits not accounted for by the gating system or something to remove them
