It's not in Nicolas Wade's article, which I now see has been unfairly maligned along with David Baltimore who's been selectively quoted to leave out the technical detail of what made the latter say the SARS-CoV-2 is a smoking gun, see the 4) A Question of Codons: https://nicholaswade.medium.com/origin-of-covid-following-th... If correct, that's getting strongly into bioengineering evidence.

You are of course more likely correct about the alignment issue, I can't find my source now, and the above is probably much stronger evidence. For the alignment you'd have to be a virologist, probably one specializing in coronaviruses, to be able to really judge this. Of course a whole bunch of biologists have shifted their focus to coronaviruses in the last year and a half.
