This was my immediate thought when I looked at the numbers, but I didn't want to be "that guy". I think if all you ever work in is Python, it's still nice even if it is a tiny improvement.
The goal with faster cpython is for small compounding improvements with each point release[0]. So in the end it should be much more than a tiny improvement.
