By chance I mapped a couple of crossings at the junction of Southchurch Boulevard & Thorpe Hall Avenue (http://osm.org/go/0EGQ1kp6R--). The first is not marked on the roadways, but is an asphalt path across the central reservation. The second has zebra crossings on both carriageways and a footway between them.
Just now I've added a landuse=grass area on the easternmost end of Southchurch Boulevard. This does nothing for routing, but does help with visually interpretation of the map. My impression was that in this area most natural desire lines for crossing both roads are broadly met by OSM as it stands. It is always possible to see if there are other observable desire lines just by looking for paths worn across the grass. These can be added, and I believe there is even a tag <http://taginfo.openstreetmap.org/tags/path=desire> which can be added to reflect that these paths are just desire lines, not anything official or maintained. My impression is that bus stop access is probably the major factor which might result in the creation of such paths. It's always possible that someone somewhere in OSM has invented a tag for annotating ways whose purpose is solely for routing. (Some imported data on waterways has something termed an ArtificialPath for linking linear elements (streams, rivers) within an area element (lake or reservoir).
