This seems consistent with coherence being not a constraint but a dimension of optimization pressure among several/​many? Like environments that money pump more reliably will have stronger coherence pressure, but also the creature might just install a cheap hack for avoiding that particular pump (if narrow) which then loosens the coherence pressure (coherence pressure sounds expensive, so workarounds are good deals).
