There is much to add to this list. For instance the task of writing concise copy. It can take a lot of work to get there. A simple form may require only a few sentences to guide someone through but getting everything in a logical order can require several iterations. The finished result may be the result of many, many tests. Sometimes only working with the form and building the backend for it is how to get to the result. In fact you need to know that problem space to get there. The finished results should look effortless and simple but there may be many commits leading to getting there.
