With CDI scopes, we end up with a few "stateful" scopes (@SessionScoped, but also @ConversationScoped, @ViewScoped...) so why not having the same functionality in CDI ? @PreDestroy and @PostConstruct are already part of JSR 250. So why not having @PostActivate and @PrePassivate as well so they could be used in every bean ?

I always found @Remove extremely weird, I think removing a bean instance should be an explicit action, not an side effect of calling some other method.
