That makes a lot sense, thank you! I was stuck on the visualization analogy where choosing the wrong axes for the histogram makes it useless (e.g., when all the data falls into the same bin you can't see the shape of the distribution). But for answering quantile, this doesn't matter. Even if P1 and P99 are in the same bin you still know what their values are up to a multiplicative constant. Fantastic!
