Feature or enhancement

Proposal:

PYTHON_GIL=0 python ... or python -Xgil=0 ... should disable the GIL at runtime, in Py_GIL_DISABLED builds. This will be similar in spirit to colesbury/nogil-3.12@f546dbf16a.

Has this already been discussed elsewhere?

I have already discussed this feature proposal on Discourse
