It seems that PyPy is not being actively developed anymore and is phased out even by numpy (https://github.com/numpy/numpy/issues/30416). There's no official statement from the project, but the numpy issue is from a PyPy developer. I added a warning to avoid users assuming PyPy properly supported and developed Python distribution, and in anticipation of PyPy being eventually, slowly deprecated. --------- Co-authored-by: Tomasz Kramkowski <tom@astral.sh>
