Description

Proposal:

Doc/deprecations/c-api-pending-removal-in-3.16.rst lists 26 C APIs due to be removed in 3.16. All 26 are still in Include/ on main, still marked Py_DEPRECATED:

  • PySys_SetArgv, PySys_SetArgvEx, Py_SetProgramName, Py_SetPythonHome
  • the 21 Py_* global configuration variables (GH-133654 open, draft)
  • Py_UNICODE

Py_SetProgramName and PySys_SetArgv were removed once in 3.13 and restored in gh-117987 after it broke packages, so this is not a mechanical removal.

The file is also not included from Doc/deprecations/index.rst, so these deprecations are currently not listed on the Deprecations page.

Has this already been discussed elsewhere?

Research direction

Review Doc/deprecations/c-api-pending-removal-in-3.16.rst, Doc/deprecations/index.rst, and the affected declarations in Include/. Check linked PRs gh-154758 and gh-154759, plus GH-133654 for the global configuration variables. Done means the removal status is resolved for all listed APIs and the deprecations page includes the relevant file.
