If you want forks there are forks. Off the top of my head, Redhat is supporting Python 2 for several more years and there's a project called Tauthon [1] that is "Python 2.8" in spirit. I'm sure there's more efforts I'm not aware of.

The push for Python 3 has been happening for over 10 years at this point. At what point do you expect people to be able to stop supporting a very outdated distribution of any software?

6 years ago my company switched to Python 3.5 and there was a big push in the community at that point to move away from Python 2. I mean Python 3 came out around the same time as Windows Vista, which has been unsupported since 2017.
