In my environments, we frequently have ancient versions of RHEL installed, sometimes with no Python at all (IIRC) or nothing better than 2.4.
That's pretty advanced as older Red Hat systems go. You're lucky it isn't 1.5.2! Getting serious, Red Hat systems have included Python for about as long as the youngest core committers have been alive, and I'm sure that goes back before they called it "Enterprise" Linux.
