Cool, good to know. /usr/bin/python has been python3 since mid-2010 on Arch Linux.
One approach would be to have a minimal script that fetches and builds a newer python, to be run by people stuck with RHEL4 forever. I have that cpython configure takes 30 seconds and build takes 50 seconds, so this could be feasible. They don't need a system-wide install.
