What if humans never experienced the population bottleneck?

(From what I know) In prehistory there was a drastic population bottleneck, iirc it was caused (maybe) by the eruption of supervolcano Toba, which brought the human population down a shitton. Then, there was a population boom, where people were breeding with their relatives, which significantly reduced genetic diversity in our species. From what I know, there are genetic differences in humans, like how most East Asians don’t have body odour. What if this bottleneck never occurred, and modern humanity was significantly more genetically diverse?
