I think it's fairly safe to let go of this claim. The WHO did an extensive report in Feb 2021 into 92 cases of potential early COVID. This included staff at WIV and used COVID tests on preserved samples. They found that none of the cases were actually COVID.
I agree with you (and so does the ACX post I cited elsewhere). I'm just saying it is a claim made by the pro-leak crowd that, if true, would be more credible than "A virus research lab was located in an area where novel viruses have tended to emerge".
