From my context, this is applicable to the drafts of Arisugawa Park, which I have been working on for 13 years and has gone through many many drafts. A lot of the added paragraphs and sections have been cringe-worthy and will never see the light of day.

That said, they involve working out new facets of familiar characters, that I didn’t realize existed. Not all of them turned out to be valid, but they have value. I wrote them because I was processing some idea and to read them today, when I have long forgotten what I considered a dead-end at the time, is instructive.
