I don't mean that "political" (in this case, "business") reasons are  
unimportant, but they can be addressed in other ways.

The advantage of decoupled release cycles isn't simplicity (though  
that's welcome as well, if attainable), but the ability to update  
library packages independently should bug fixes be needed.

I don't think this is a huge deal for the pickle module, but is more  
of an issue for some of the wrappers for external libraries.  The  
database packages (bsddb, sqlite) come to mind here, but aren't the  
only cases where independent releases make sense.  We've certainly  
seen that including the "xml" package in the standard library was  
questionable at best (and the tie to PyXML exacerbated that horribly).
