Agreed, and I mentioned that solution in the article, but I'm not so convinced this is true. It reads a bit like the "if you're a great programmer, the lack of memory safety of C isn't a problem!" argument. In theory sure, but in practice it seems CVEs keep on popping up.
It's one thing to produce a prompt injection, but another thing to produce prompt injection that avoids detection by multiple layers of such analysers.
Similar multi-layer systems are already being used, with success, for sanitising outputs from various LLM and diffusion models.
