I don't think it'd be wise to pollute the context of every single conversation with irrelevant info, especially since patches like that won't scale at all. That really throws LLMs off, and leads to situations like one of Grok's many run-ins with white genocide.
Given that every LLM-players are still looking for their market, I wouldn't be surprise if they did things that don't scale.
No need to include that specific guard rail in every prompt - just use RAG to include it where appropriate.
