My take on Worobey, et al. and Pekar, et al. is that the most significant thing to consider is that two strains of SARS-CoV-2 emerged at the same place in November-December 2019, Lineage A and Lineage B. Worobey makes strong claims based on geographic data, but I can see weaknesses in that. The genetic evidence for multiple crossovers provides a stronger indication of animal origin.
