The following C API functions were deprecated in Python 3.11 by issue #88279:

• PySys_AddWarnOptionUnicode()
• PySys_AddWarnOption()
• PySys_AddXOption()
• PySys_HasWarnOptions()
• PySys_SetArgvEx()
• PySys_SetArgv()
• PySys_SetPath()
• Py_SetPath()
• Py_SetProgramName()
• Py_SetPythonHome()
• Py_SetStandardStreamEncoding()
• _Py_SetProgramFullPath()

IMO it's now time to remove them: the new PyConfig API is available since Python 3.8: https://docs.python.org/dev/c-api/init_config.html

   Oh no, too bad, I forgot to deprecate PySys_ResetWarnOptions() in Python 3.11.

   The original issue says:

   I don't propose to schedule the removal of these functions, only mark them as deprecated in the documentation.

   What changed?

    Issue gh-88279 was in 2021.

    I wrote it in this issue description in 2023:

    IMO it's now time to remove them: the new PyConfig API is available since Python 3.8: https://docs.python.org/dev/c-api/init_config.html

    What changed in that the PyConfig API is now widely available and is a better API than the deprecated one.

    It seems a PEP is needed for a full replacement. You wrote PEP-741, there are objections against the basic concept of PEP-741 :(
