It is, but that annotation is modified in places like AbstractIdentifiableInitializableComponent to be @Nullable @NonnullAfterInit.

IdentifiedComponent and InitializableComponent can interact to form two distinct contracts:

* components which may or may not have identifiers after initialization (I don't know if we actually have any of these)

* components which must have identifiers after initialization (this is enforced by subclasses of AbstractIdentifiableInitializableComponent)

With this in mind, I don't personally find the @Nonnull annotation on getId in IdentifiableComponent very illuminating.

Definitely worth talking about on Friday.
