Hi 👋

I was trying to add a test on uvicorn, when conn.receive_data() was able to send a RemoteProtocolError without an error hint:

https://github.com/encode/uvicorn/blob/22bd00eab6dfa7145618ce6cd1acfdffea8bbe6e/uvicorn/protocols/websockets/wsproto_impl.py#L89-L94

But the thing is... In the whole wsproto source code, there's always an event_hint being sent.

Can we make event_hint mandatory here?

EDIT: See Kludex/uvicorn#1486.
