The current documentation_ of the Python-C API mentions that PySequence_Fast is part of the limited API. However, this may be a typo as all the functions interacting with a PySequence_Fast object are macros, e.g. PySequence_Fast_GET_SIZE, PySequence_Fast_GET_ITEM etc.
If this is indeed a documentation bug I'm happy to open a PR to fix this once consensus is reached.

Perhaps to be clear, there are two possibilities:
In either case the documentation should need to be clarified.
The only situation where no changes would result is if:
This is actually also still confusing and should be mentioned clearly.
