Publishing Query objects as Web Services in NAV 2013

I’m halfway through a complicated upgrade to 2013 RTM from 2009 SP1. We rely upon SOAP web services to integrate with .NET application using SOAP

While I was configuring the web services I noticed the query object was available for publishing, Alas when I tried to publish a query it wasn’t visible within the SOAP discovery list on the services endpoint.

Are queries available as OData only or is there something more sinister going on here?
