If you require better AF tracking in low-light situations, I think the answer is pretty clear. That ability looks like sealing the deal for me, not that I follow zig-zagging bicycles in dimly-lit velodromes.
It’ll be interesting to get some impressions from kenspo, as he works often in variable indoor lighting conditions, with moving subjects.
