Imagine if the author of the novel had to write those irrelevant scenes anyway in order to get to the good stuff. There might be someone, a literature academic for example, who would want to study that material. It wouldn't be for everyone but there are some who might want access to it. My point is that we are generating this history anyway, so why throw it out? There may be someone who wants to see how the code has evolved. Plus, nobody says you have to watch stuff that is not interesting. There are ways to filter out things you aren't interested in.
