Well, it might depend on what you mean by "deployment time" and "fully
deployed".  I can't guarantee that someone won't write application
initialization code that generates beans which need validation.  So to
be more specific, it needs to be initialized by the time
ServletContextListeners run.  That's the earliest that JSF would
actually need to use it.
