Yes, if the underlying layer’s hash changes then it has to be rebuilt. But if you just change index.html it caches the other layers and builds are very quick.

My issue with Buildpacks is that it looks like a glorified bash script (which is a skill I am not bashing — pun not intended) whereas a dockerfile is much more human readable and the idea of layers, for a guy coming from a systems background, is much more intuitive for me. The analogy of a very lightweight VM makes perfect sense to me which means I’m much more productive with it.
