I'm probably unable to catch up on this whole thread right now, but  
having been recently defeated by DeprecationWarnings when attempting  
to update Launchpad to Python 2.6, I'd say the one thing that would  
have really helped us is an environment variable tied to -W, e.g  
$PYTHONWARNINGS.  If I could have shut up DeprecationWarnings with one  
wave of my magic setenv, I think things would have gone much quicker  
for us.
