What should we do differently depending on the outcome?

The miasma alternative for cholera is another excellent illustration of my point, not yours. The answer to whether miasma theory or contaminated wells was correct very obviously had bearing on how you’d mitigate the problem, and this characteristic was totally evident even before answering the question.

If someone could specifically state what we should do differently depending on the answer, I’m amenable to it. But you haven’t done that because the answer is: nothing!
