/**
 * Extension point that omits {@link ServletContainerInitializer ServletContainerInitializers} annotated with
 * {@link RegisterRestClient}. If we try and initialise these interfaces Jersey will fail them on validation (correctly)
 * since you will end up with a duplicate mapping (the interface itself against the actual endpoint implementation).
 *
 * Using an extension mechanism rather than having this check directly in
 * {@link org.glassfish.web.loader.ServletContainerInitializerUtil} allows us to avoid pulling MicroProfile APIs into
 * the core server as a dependency.
