    To me, most uses of path.py are small incremental improvements over 
os.path rather than being compelling. Do a number of small improvements 
add up to be large enough to make this change?  There is a cost to the 
change as there will be two libraries that have to be known to 
understand code. Does someone have an example application that moved to 
path.py with a decrease in errors or noticeable decrease in complexity? 
Could all path manipulation code be switched or is coverage incomplete?

    The duplication argument should be answered by looking at all the 
relevant modules and finding a coherent set of features that work with 
path.py without overlap so that the obsolete methods can be deprecated. 
If adding path.py leads to a fuzzy overlapping situation where os.path 
is occasionally useful then we are complicating the user's life rather 
than simplifying it.
