I'm not sure that leaving out refcounting here is safe. It wouldn't make much sense, but I don't see any reason the IProxyProvider couldn't addref and save this object past the event lifetime.

Actually I could see a GC'd environment like Mono or .NET incidentally doing that.

This doesn't make a lot of sense to me. Why does the IProxyProviderWinEventSink interface accept an event id if the "wrong" one is just going to be ignored?
