I'm curious if there's going to be some community supported fork.
Software using Python 2.7 won't magically disappear and I believe there is going to be a demand after fixes.
(I know about Tauthon but I don't think it applies here ...)
There is Tauthon[0] that (they said) also backported several features in non-backwards compatibility breaking ways, but the last commit to the repo was from December. Perhaps after running it for 3-4 years (and faced hostility from some Python devs - i remember at some point being downvoted just for mentioning it on Reddit), the maintainer got tired of it?
