As far as I can tell this is a false premise. The scientific consensus on zoonotic origin was never really considered conclusive by anyone and was never really sold as being conclusive. There was a very strong backlash against the ridiculous theories spread by people like Tom Cotton that virus was engineered that absolutely soured the debate. And people like Trump and his sycophants who didn't just suggest lab leak but declared it as being overwhelmingly likely. That made honest debate extremely difficult. And even know the hand-wringing of "oh now they were right all along" is even worse. There was not then nor is there now sufficient evidence to declare this a settled debate. Trump is and was wrong. And Cotton shot himself the foot by ruining his credibility before trying to reset his opinion. In reality, we don't know. Zoonotic remains most likely. More investigation is warranted but is unlikely to turn up a smoking gun.
