What about removing a user from chat? What if the shared key is leaked? How do you deliver the key to the new user? Who provisions new keys if a shared key is leaked? There are a variety of problems (all solvable/already solved, yes) with the shared secret strategy, and addressing them costs money and time.

Because we all know that otherwise, security will not be part of the minimum viable product, and the consumer can't tell the difference. (Obviously, the state of the art answer to your technical questions is the double ratchet algorithm.)
