For me, my best approximation of "sane bleeding edge" is between Fedora and Arch, each with pros and cons. The thing I love so much about Arch and what I believe is an extremely underrated feature of rolling release distros is that everyone is on the exact same page. There is only one supported version of everything, and that's what's currently in the repos. If something breaks you can go on the forum or the subreddit or whatever and there will be someone else with your problem and someone probably already has a workaround. Sounds kinda cursed, but running something like Debian sid sucks because there's not many other people doing that. Meanwhile with Arch, there's plenty of people doing all sorts of wacky things, the wiki is really good, and the AUR hugely lowers the burden of random things you installed that weren't provided in repos that you have to remember how to build and update every once in a while. None of this is relevant to your Python example though.
