Extensions built for Python 2.3.x work fine with 2.3.x for any x 
assuming everything else that matters is the same... but there are 
plenty of outside factors that could have changed that would at least 
require a little preparation to make a package built for 10.3 work for 
10.4 (or vice versa, when possible).

Only if you want to be.  Python 2.4.1 is the only Python I "support".  
I still build packages for 2.3, only because it takes an extra few 
seconds to do so, but I don't test them anymore.
