I can certainly see the appeal of having neat commits but I tend not to worry about them. On a couple of occasions, with my university writing, having a immutable history helped me figure out, for example, how something had ended up in a final draft without citation. I'd deleted the citation which was a quick URL paste in a comment block in an earlier draft, and I'd never saved it to zotero. If I'd been able to tidy up my commits I'd likely have lost it completely.
