The idea of (at least one) population bottleneck in the evolutionary history of humans is fairly widely accepted. I haven't reviewed the paper or methods but generally their results fit the range of expectations of many in the field.
This new paper is interesting in that they developed a new method in population genomics specifically to attempt to pin down all of: the time, the duration, and the size of the population.
There are many earlier papers describing different methods for arriving at similar conclusions. The below paper used similar genetic signatures from bottleneck events such as the loss of rare alleles. Their methods were different. It explains one such process fairly well and is available to read:
