Comment (by brucedechant):

 There is code for the failback method still there.

 I tried using the OGR provider to connect to a SHP file (Sample World
 Countries) and I get back a useless SpatialContext. Here are the results:

 <?xml version="1.0" encoding="UTF-8"?>
 <FdoSpatialContextList>
 <ProviderName></ProviderName>
 </FdoSpatialContextList>

 In the above the provider isn't even listed. The interesting thing is that
 I can use the feature source preview to see the attribute data just fine.
 So at least the OGR provider appears to be partially working, but there
 looks to be a bug in the OGR provider for returning spatial context
 information.

 So even if the SelectAggregates call fails there is no spatial context
 information to fall back on and so the preview still fails.
