Is this the ChrisJones patch that is labeled "Not fully working / stalled" 
you are referring to?

For 7.x, all we can really go back is RSS, from what I can tell ... it 
won't be until 8.x(?) that we will be able to get more accurate ... ?  And 
even then, it will be a patch we have to add, not stuff that has been yet 
integrated into 8.x?
