FWIW the mere fact that the goblin stuff is necessary and is in the system prompt suggests to me that OpenAI's approach of training ridiculously large models that can do everything for everyone is hopelessly cooked.

Though I concede it is not that much different than straightening the tie of your most valuable employee before you unwisely put them in front of a client and saying "please don't tell them about the regressions they didn't notice and remember, they don't want things explained in allegories drawn from the Silmarillion".
