Do you mean that Singleton should be abandoned by CDI? Or do you mean to clarify its role and/or implement proper lifecycle support for them?

Actually there's no singleton scope and corresponding built-in context
defined in the CDI spec. Though Weld API contains
org.jboss.weld.context.SingletonContext. Also the docs are outdated
(chapter 5.4. The singleton pseudo-scope). I think relevant classes
should be deprecated and the docs updated.

With regard to lifecycle callbacks - Weld only invalidates application
context during shutdown right now [1].
