Debugging could be another reason, I suspect? I remember when I tried to use the interface, there is really no API that tells me "did I add this stat successfully and/or correctly?" I think having a general print so that developer/debugging folk could just 'grep mystat' to verify that would be helpful in the future.
Otherwise, they have to write code themselves to do the dirty print...
