Are you denying the problem of Backwards compatibility with python versions? It was and still is a big problem today. I'm still seeing the affects of that though many communities. I don't really think it's only good for tinkering but I know its developers clearly do, otherwise they wouldn't have subjected us to the transition from python 2.7 to python 3 and the fallout that followed, and people wouldn't have been so eager to comply with them dropping python 2.7 support in all their python integrated envionments before you could say bitrot.
Yeah somehow that doesn't give me much confidence for the future.
