I honestly wouldn't expect that flag to last forever because it exists purely to help with Python 2 -> 3 transitions. Since it fundamentally changes how things like comparison and `str()` work it isn't something to flip on needlessly and you would be better off using a type checker or linter to look for those sorts of errors.
As such, changing the C API specifically for this flag isn't something I personally would want to see.
