STA and rear center are interdependent for making geometry work. Long rear centres can be a treatment for too-slack STAs, so that the weight balance isn't in permanent wheelie position. Similarly, you can enjoy the benefits of a short rear centre if the STA is steep enough to leave you in a balanced climbing position, and the reach is long enough to keep that balance forward on the down.
My point is, I think it missed a lot to pass judgement on a bike looking at numbers in isolation. Short chain stays have fallen out of fashion for some reason, but when paired with numbers that keep the weight balance healthy, what's the downside? All it really changes is how close your feet are to the rear axle, and how much you need to bend at the hips to stay centred on the bike.
