Is there a full list of possible events and maybe even a flow graph?
The happy path works well but I am concerned that there might arrive events I just did not consider arriving because I don’t know them.
Scroll a bit further, and you get the possible server-sent-events (to be transmitted in server-sent-events) along with the type of object they are producing.
The API reference being a reference, any additions should be noted there, with you gracefully dropping unknown types.
I could see the usefulness of opening this up to other events, for example, a thread.message.annotation event to markup a citation reference just produced.
