I actually pondered not including access to the underlying streams at all.  The reason is that the streams simply provide access to the raw bytes in the PDB file.  All of the information present in the streams is available through the typed methods as well.  But I figured it was useful still for the dumper.  From what I can tell, the dumper will be the only real client of the stream data, so just returning the name sems kind of reasonable.  Another thing is that it's not documented what all of the different streams that might be returned are.  So far I've observed a few different ones through some dumps I've run on my own, but they're not always the same, so there could be some we don't know about.
