I'm sorry, I don't understand what 'changed'. Isn't that rule exactly WHY 3.9 is the removal point? Python 2.7 is no longer supported, and its final post-support release is scheduled earlier than 3.9's first beta and feature freeze. Doesn't that mean that PEP 4 is being followed precisely? What have I misunderstood?
