Increase WebSocket Connection Limit
If EventSub is aiming to replace IRC, increasing the WebSocket-based connection limit beyond 3 simultaneous connections is necessary for projects that run client-side and connect directly to Twitch independently. Streamers can modify and manipulate copies of such files in the filesystem and/or in OBS, all using the same authentication token, which, even if not simultaneously visible, may simultaneously continue running to prevent awkward failure of functionality during transitions.
I don't think a limit anything like the new IRC maximum of 100 is necessary -- if someone has 100 copies of one thing in OBS, this limit isn't going to be the only issue -- but double the current number (meaning 6 instead of 3) seems like a good start.
