What about the other major change to Python's implementation: free threading? Has it lived up to expectations? I assume it's not also in doubt, despite Guido recently saying "Personally I wish we’d stuck with the GIL"? [0]

Getting a JIT from underwhelming to actually good is always going to be a whole lot of iterative work to remove blocking parts of the existing implementation. In Ruby-land we have had a good JIT for a while now, but it took many release cycles and a ton of resources before it was able to outperform the non JITed version when using Rails. Don't expect quick fixes that make great strides and any investments in it needs to be persistent and apply over time.
It boggles my mind that it apparently is the case that such a popular language as Python isn't able to get the resources to do this.
