Have you considered that having 200 or 300 keyword arguments might
already kill performance? I don't think our function invocation code is
tuned for such a number.

Was there an old ticket open? I have only seen a piece of code on
python-ideas. Regardless, whether one or the other doesn't really
matter, as long as it's recorded somewhere :)
