After delay is implemented, filtering just for a relay won't be costly, thereby the relay property isn't really needed, and just makes the API more complicated. It can probably be removed, but it's good to evaluate on a reference implementation. Anyways it's probably better to leave it, as different implementations may use different methods for subscribing.
