Wide events are good, but watch out they don't become "god events". The event that every service needs to ingest, and, therefore, if there's new data that a service needs then we just add it onto the god event, because, conveniently, it's already being ingested. Before too long, the query that generates the wide event is getting so complex it's setting the db on fire. Like anything, there are trade offs; practical limits to how wide an event should reasonably become.
