描述
Feature or enhancement
Proposal:
Take the example of Py_SetPythonHome().
It has been deprecated in 3.11, and we should now do things with PyConfig (added in 3.8).
But it is also part of the limited API. So it should not actually disappear, and someone building with Py_Limited_API<3.8 does not have the available symbols to use the non deprecated variant.
So every developer building with the limited API that cares about the warning will have to study each deprecated function, and if the non deprecated vairant is not in the stable API, add local deprecation warning disable code.
The proposal:
When Py_LimitedAPI is defined, Py_Deprecated should not trigger a warning if The deprecation version is greater than the limited API version selected by the macro (3.2 if the macro is empty, otherwise, the version value in Py_Limited_API), since we are really compiling for a lower version of python
I can probably do the PR myself if it is accepted
Has this already been discussed elsewhere?

调研方向
首先定位 CPython 头文件中 Py_DEPRECATED 和 Py_Limited_API 的定义和使用位置,然后以 Py_SetPythonHome 的声明为具体示例进行跟踪。检查选定的 limited-API 版本如何影响弃用警告,并验证只有在该 API 版本中无法使用替代项时才会抑制警告。
