Smallpox never became non pandemic on its own.
We have no idea if this will either.
It may mutate and become totally airborne before it lowers its mortality rate.
Still, even a 30% mortality rate and airborne would be a herd thinner fur sure.
Small pox destroyed the American Indians. Whole tribes died in a fortnight. Do we want to see that again?

On the contrary, I think it did grow weaker. It developed a strain called “cow pox” — which then became the basis for the earliest vaccinations.

Sure. You’re right, insofar as we can’t make an exact prediction.
But you can say the same about ANY possible threat. All we can go on are the probabilities, which tell us that most viruses eventually weaken.

In Africa? No doubt about it.
But in the USA? Just won’t happen, in my opinion, because of our modern means of sanitation, public health monitoring & controls, good hospitals, good docs and so forth.
(Remember a few years ago when West Nile disease first hit our shores? The news media were full of apocalyptic predictions about the looming death rates. But like so many other diseases, West Nile just faded into the background. It’s still there, but simply not a major threat.)
