I also think we should be thinking more long-term. How understandable is the history when you're trying to figure out why something changed? I usually try to tell the story of what changes are being made rather than treating every clump of commits as a "PR" that's just going to be squashed together anyway. I think a lot of valuable information is lost by doing that. But I realize that that train has left the station for most, so I'll just shut up now.
