I find your critique very interesting from a perspective-angle: why are you using words like "accommodate," and "foibles," for LLMs? It's not humanoid or sentient: it's a cleverly-designed software tool, not intelligence.

It's not insane at all for humans to alter their behavior with a tool: you grip a hammer or a gun a certain way because you learned not to hold it backwards. If you observe a child playing with a serious tool, like scissors, as if it were a doll, you'd immediately course correct the child and educate how to re-approach the topic. But that is because an adult with prior knowledge observed the situation prior to an accident, so rules are defined.

This blog's suggested rules are exactly the sort of method to aid in insulation from harm.
