Thanks for your feedback everyone. Given the overwhelmingly negative response, we'll drop this line of investigation.

If more people bring up the same request in the future (unlikely), feel free to reach out to us for some extra set of hands. Given the initial poking, I still think a "reasonable subset" might be "reasonably easy"; IMHO more a process/maintenance/ROI question than a strictly technical one.

If you mean "writing an alternative Python interpreter", that's not of any interest. If you mean "eliminating GIL from mission-critical parts of the code" -- we've done that many times, with good success and only moderate pain. The current "const" question was a probe about the cost of bringing the worlds a little closer.
