Better for whom? Certainly not for the labs. It's far better for the labs to draw their own conclusions from the leak, privately, at their own pace. Also, there's a significant financial disincentive: funding for gain of function research will be severely impacted by recognizing the lab leak as the most plausible explanation.
Right now I'd conclude that you can accidentally release things from labs with virtually no consequences. Just make sure that a similar virus exists naturally somewhere on the same continent, don't share any internal records, don't let your staff talk to the press, and you have plausible deniability.
