I think removing //bordered reference is more appropriate, because you have already explained it above.

I removed my extra comment line, since it's neither a workaround nor a corner case.

So deprecated Py_GetPath() should be replaced with PySys_GetObject("base_prefix"), instead of PySys_GetObject("prefix")?

Yeah, the equivalent of Py_GetPath / Py_GetPrefix should be sys.base_prefix, since sys.prefix takes venv into consideration. I think it's necessary to clarify it in their deprecation notes: https://docs.python.org/3/c-api/init.html#c.Py_GetPrefix
