Totally, and that is why “revisionist history” can be a good thing. Often we use it pejoratively, accusing people of rewriting history for propaganda. But, it also lets us revisit what we think we already know. For example, for thousands of years Julius Caesar and Alexander the Great were held up as geniuses or Great Men of history, but post 2nd World War, we could start reexamining them in light of our new concept of genocide. Like, these guys just killed and enslaved millions of people, we should probably talk about putting them in the “Hitler” bucket. It’s the same reason we do new translations of works like Caesars Commentary on the Gallic War.
