Is MoCa still supported with the XB10?

I just recently got the new XB10 and was looking into MoCa as a solution for the gap between gateway and devices in my house. The MoCa setting no longer appears in the gateway web portal, however, it is still accessible by manually navigating to moca.jst. The real problem comes when enabling the setting as when I hit save it gives the "Operation in progress..." only to finish and revert the setting to disabled. The fact that its not a clearly advertised option makes me worry that it is no longer supported. Any ideas or experience? Thanks all.
