I think the point is that we weren't approaching the limit on release day.
Agreed that 32B is the best way forward for GPUs, I would personally like to see the Global and world record points on the 32B bench and just hardware on 1B. Just to help with the longevity of the benchmark.
On a side note I did give it a quick run yesterday and I quite like the benchmark, it's nice and easy to use with built in tweaking too
