Hello Pythonistas,

Python 3.13 has an experimental JIT compiler:

https://docs.python.org/dev/whatsnew/3.13.html#experimental-jit-compiler

Enabling it is a configure (hence build-time) option.

How do we handle this in Fedora?

- We can keep it disabled, as it is experimental.
- We can enable it, but be ready to revert if it causes problems.
- We can add yet another build variant, but we already have 4 of those
(regular, debug, freethreading, freethreading-debug), so I'd rather not make it
6 (or 8, if we include freethreading+jit combinations). I don't know yet if it
would be co-installable.

Opinions?
