As I said, this would double the amount of python module
recipe builds.

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.
