Hi! This might be interesting for you. The JSF EG is curretly holding a public poll [1] about whether they should deprecate their own javax.faces.bean.ManagedBean stuff. This means they would further support it, but not add any new features.
Instead all ManagedBean features will be provided on top of the CDI-1.0 (JSR-299) or CDI-1.1 (JSR-346) specifications. Please feel free to vote yourself, it's a public vote. LieGrue, strub [1] http://pollpigeon.com/should-we-deprecate-managed-beans-in-jsf-22/r/166960/
