My question is how important is this functionality? Do I really need to go through and add an argument to marshal.loads or some new function just to set cofilename to something that someone explicitly set in a .pyc file? Or I can let this go and have this be the one place where builtins.import and importlib.import differ and just not worry about it? Just to be clear, this would show up if I: had a python tree built and run stuff from it symlinked to that tree from somewhere else ran stuff from that somewhere else

Right; the code object would think it was loaded from the original location it was created at instead of where it actually is. Now why someone would want to move their .pyc files around instead of recompiling I don't know short of not wanting to send someone source.
