I think you misread what I said. I said "could help us" which just implies it's a distant possibility. I am aware that it's an extremely low probability event, but not an impossible one, for example in 200 years they might find a universal beta coronavirus vaccine based on a general stem and not on a variant specific spike.

More information in this case is better outcomes regardless. We can't just accept the current state of affairs and do nothing if there are still avenues of improvement that don't involve pretending like COVID is a mild disease or forcing quarantines whenever some worse variants shows up.

Whether it will jump back from deer or dogs (two animals aside from minks who i remember testing positive for sars-cov-2) back to humans is a huge if (hasn't happened so far as far as I remember, or if it did, it couldn't have been more than ballpark ~5 cases), but I don't disagree that it might happen once more, since I'm not a lab leak guy.
