I almost never revisit parts of the page I've already written, they may sit there for years untouched, or I may delete them and do a whole different layout from time to time.
It's definitely painful to edit small details after months of not seeing the code, so it's not for people that need to do that often.
I also understand that for most people, indentation is not a good separator. I worked with Python for so many years, that I probably view white space differently than others. Symbols are visual overload for me, I just need 4 spaces to see structure and separation.
