People should remember that evolution is a strictly heuristic algorithm.
Consider there is nothing biologically impossible about humans having in built radio systems or deployable wheels but they don't because the intermiediary stages confer no advantages. Evolution tries to walk a species up hill but it can only put us on top of the nearest hill, not find the highest mountain.
So the problem with this virus is that, given the long infection period, there is no immediate and obvious benefit to being less deadly. If there was to be a perfectly designed virus you would make it take a long time to kill you because there would be a weaker selection pressure to make the thing less harmful.
That all being said it will still probably become more benign over time, and you would hope it would be more likely to mutate into something less harmful than something more harmful.
