I find that easier. I don’t understand how mere indentation would make it more difficult to read rather than less. I indent every heading of my documents, for instance, like Revision - Stack Overflow demonstrates.
That’s a Logical extreme - Wikipedia. It’s irrelevant. Cognitive difficulty, like any other attribute discussed here, has a non-negligible Benefit–cost ratio - Wikipedia, so it should be considered in earnest like any other attribute. I don’t understand why you would mention that.
