But the group structure in the profile has a copy of the founder's shared_state.founder_public_key (group_pack.c#L293) So if the profile being copied onto a new device is the profile of the founder, then this key would need to be updated too. (Conversely, does that mean if I copy a profile and update the shared_state.founder_public_key with my own key, do I become the group's founder?)

The chat->chat_secret_key is all zeros, I assume in everyone but the founder's
profile.
