Does JSF 2.2 support window scope ?

[Stephen More]

When using JSF 2.1 in order to utilze window scope ( like a session per
window ) I was required to utilize CODI. I now see that JSF 2.2 has some
support for ClientWindow. Can I stop using CODI and utilize the built in
features in 2.2 for session per window or I should I migrate to DeltaSpike
for my window scoping needs ?
