I think group e2ee is overblown and self-defeating in principle. Good luck auditing a ratcheting e2ee algo. Plus it breaks often, and group encryption is defeated by any user in the chat.

Direct e2ee is far simpler and can be expanded to small groups without the need for complex ratcheting trees. Anything larger and you may as well fall-back to client-server with e2e communications.
