Sorry, I don't ask to stop optimizing C extension. I'm asking to stop
to use low-level C API like PyTuple_GET_ITEM() if the modified code is
the not the performance bottleneck.
As long as some people need that API, you'll have to maintain it
anyway, even if _less_ people use it. Ingesting lists and tuples as
fast as possible is important for some use cases. I have worked
personally on some of them (on e.g. Numba or PyArrow).
