It's really not mainstream amongst virologists.. as has been demonstrated by repeatedly debunking the latest gish gallop papers, there's literally zero evidence for lab manipulation of the sars cov2 virus. It's vaguely plausible that the virus could have been captured in the wild and then leaked, but even that seems extremely unlikely given the two separate market lineages and timeline of the earliest cases.
Stricter control of GoF makes a lot of sense but the reason everyone was studying coronavirus pandemics in the first place is because we'd had several near misses and everyone in the virology community knew it was only a matter of time before the right circumstances allowed a spillover to do exactly what Covid19 did.
