Would you mind changing this to `#broadcast_subscriber_events?` and `#broadcast_subscriber_events=`? I know it's a bit pedantic but I feel as though keeping it as just `#subscriber_events?` is a bit too vague and could possibly conflict with other config options involving channel subscribers added later.

Also, when you add a config option, please add it to the config file generator along with a brief description of what enabling it will do.
