It seems that PyPy is not being actively developed anymore and is phased out even by numpy (numpy/numpy#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.

Is it intentional that the note is duplicated?

It feels like it might be, but they're very close together - seems somewhat excessive?

!!! note

PyPy is [not actively developed anymore](https://github.com/numpy/numpy/issues/30416) and
supports only up to Python 3.11.

Yeah I think maybe let's just note it on the managed distributions section?
