For 3.13 and above the experimental JIT could be activated in the build but disabled by default. Adding --enable-experimental-jit=yes-off carries minimal risk and allows end-users to activate JIT support with the $PYTHON_JIT environment variable. Mostly creating this for tracking purposes.

This looks to be relatively low risk but would require installing LLVM during the compile. Shouldn't increase the resulting image size as it can be removed before the end of the build step.
