on May 7, 2026 I've added
builtins.ellipsisto the checklist in #7580. (@JelleZijlstra originally listed it in the issue, but for some reason I hadn't included it in my list later in the thread.) Apart from that, Python 3.9 has now been removed.
Python 3.9 reached its end-of-life phase on 2025-10-31 (PEP 596).
