That's only the interpreter released by the Python Software Foundation itself. I can't even remember how long its been since I installed their interpreter but probably at least a decade. In recent years its been Miniforge and before that was Anaconda (before they changed their licensing terms for orgs with 200+ people).

That said, its fair enough to drop support for a particular version whenever you want. I'm merely pointing out that there other providers of Python interpreters that are both widely used and support older versions longer. Other folks mentioned OS distributed doing the same already, but personally I don't use the system interpreter and just leave it alone for whatever the distro needs it for.
