I am not sure about PyPi (I'm not an intense python user), but I think you are mixing two problems here. One is having some bindings in the git repo the other is packaging. If we are not shipping python bindings in a separate package (like we do for qemu for instance) or the -python package is not optional, then this is the problem. Personally, I think if we do this, then python bindings will suffer from the decision every time somebody introduces an API extension. Because sooner or later we will forget to update the python bindings. Anyway - I don't wanna be a show stopper, so take this as my concerns not a vote for or against.
