Agreed.  IIRC the main argument for making Python a user is that scripts 
could be working on objects when they are suddenly deleted in the 
Blender GUI, and then the script would fail.  I believe that was before 
the fakeUser support was added, although I don't really know what that 
does.  I think Michael Reimpell was one of the proponents of adding 
this; maybe he's still lurking here and can give some insight.
