See the Red Hat bugzilla ticket I created for a different reason (old bitbake needs old python, still a parallel installation use case): https://bugzilla.redhat.com/show_bug.cgi?id=2418374 "We don't have the human power to maintain several separate Python stacks packaged as RPM packages in Fedora." Python 3.14.x is present in Fedora 43, only without freethreading. I expect they won't do a parallel installation with freethreading, either, due to the same reason. When they switch, it will be all or nothing.
