Please check if there are projects in the wild that use this. See for instance the case of PyWeakRef_GetObject where we delayed the removal for now until less projects are using it. And also, we should coordinate with the compat project. Finally, add a section for this removal in What's New as well as possible fallbacks.

I have some rough and preliminary search in GitHub and find some projects like:

• https://github.com/plotdevice/plotdevice
• https://github.com/crftwr/keyhac-win
• https://github.com/renpy/renpyweb

still use these C functions.

I can have a more detail exploration for popular PyPI packages later.

@picnixz I search the top 300 popular PyPI packages and find PySys_SetArgv appears in the following 2:

• cython
• orjson

Well cython is a major project that we don't want to break. orjson is, iirc, simd-accelerated JSON so we don't want to break it either. They should first upgrade their code and then we'll remove the functions on our side I think.
