Cluster Aware Updating with SQL Server 2012 or later and Always On Availability Groups

I've been reading some documentation from Microsoft regarding an AWESOME feature and noticed my clippings are "relatively" old.  Microsoft came out with a document called "Patching SQL Server Failover Cluster Instances with Cluster-Aware Updating (CAU)" which basically states that using this awesome feature with a cluster with Always On is not supported.

So... My questions:

Is that document is still correct on SQL Server 2012?  Meaning, does a subsequent version fix this?

Does SQL Server 2014 solve this?

How about SQL Server 2016?

My shop is pretty consistently using Clusters with AO, so I'm dying to find a supportable way to do this.

Thanks,

Keith
