Alternative Proxies:
In NumPy we use
_Py_HashDoublefor our floating point hashing needs and that seems like a pretty good candiate for the unstable API to me: #91744 (comment) and #101101 (comment).However, the function is currently removed rather than made unstable (to my understanding). While it should probably be easy enough to vendor what we needed, I would prefer the unstable API tier, it gives a better sense of having the required identical hashing.
