Struct NoopCeremonyEventSubscriber 

pub struct NoopCeremonyEventSubscriber;

The subscriber a stream gets when nothing is projecting from it.

Its own type rather than an Option, for the reason NoopMetricsRecorder is one: the append path notifies unconditionally, so there is no branch to get wrong and no configuration in which the notification is skipped.
