I am a bit frustrated about this situation. We could hide almost 
everything from the application to leak very little (but not get the 
best user experience), or we could expose a lot of data to the app and 
leak at lot (but get a better user experience). Then you hear two 
extremes to guide the decisions: leak as little as ever possible; or 
this is a lost battle anyway so don't bother. Sigh.
