> What prevents a new update to revert this or cause other safety problem?

One would hope it's a culture of safety first at Tesla where all software changes are extensively reviewed, heavily tested in the real world and using whatever kind of simulations are possible, deployed in a reasonable manner to a small set of cars and only deployed to the main population of cars after a satisfactory amount of time.

Yeah, it's pretty scary to know the braking software in your car was tested for less than a week.
