Neither the protocol, nor the technologies it uses, nor the capabilities it exposes are new or even novel.

What is novel is the "yolo vibe code protocol with complete disregard to any engineering practices, and not even reading at least something about that was there before". That is, it's world's first widely used vibe-coded protocol.

That's why you have one-way protocols awkwardly wrapped to support two-way communication (are they on their third already?). That's why auth is an afterthought. That's why there's no timeout coordination.
