It is thoroughly unsurprising to me that most scientific publications would take a stance against releasing studies or articles considering option two or three, as right-wing media and politicians were/are fishing for anything with a suitable scientific veneer they could throw out as evidence of someone to blame. (And its not hard to see why - telling your constituents they have to deal with job losses, family deaths and lockdowns because someone in China ate a bat leaves people without something to blame, and the politicians tend to be the closest relevant people.) Given the amount of anti-asian racism/crime/murder we've seen spiking in the last year, I think the publications' stances (and the more mainstream media) to lean heavily towards option one is understandable - no one wants to be the used as justification for hate crimes or political action a la the Iraq war buildup.
Perhaps in another year or two things will have cooled down enough that stuff like this can be considered without collateral damage.
One other reason it's way too hot to discuss right now: it would suggest that scientists were at least partly to blame for the pandemic. Even if you're not Chinese, you might not want to be discussing that idea if you were a scientist yourself.
In fact it’s the opposite we need to have the hard conversations as early as possible.
